Graphing exponential functions and logarithms involves understanding the key characteristics of these functions and how they are represented on a graph.
Asymptotes: The graph of an exponential function does not have any asymptotes.
Domain and range: The domain and range of an exponential function are all real numbers.
Increasing or decreasing: An exponential function is always increasing.
Shape: The graph of an exponential function is concave up.
y-intercept: The y-intercept is (0,1)
x-intercept: The x-intercept does not exist.
To graph an exponential function, you can start by plotting the y-intercept (0,1) on the graph. Then, you can use the information about the shape of the graph (concave up) and the increasing nature of the function to determine the general shape of the graph.

Find the domain and range of the function graphed below. PLEASE SHOW YOUR WORK!!
The domain and range of the function on the graph are:
D: [-2, 1)R: [0, 4]How to find the domain and range of the function below?Remember that for any function y = f(x), we define the domain as the set of possible inputs (possible values of x) and the range is the set of the possible outputs of the function (possible values of y).
To find the domain we need to look at the horizontal axis. The minimum is at x = -2 with a colored circle, so x = -2 belongs to the domain.
The largest value is at x = 1, now with an open circle, then this value does not belong to the domain. Thus the domain is:
D: [-2, 1)
For the range we need to look at the vertical axis, the minimum is at zero and the maximum at 4, then the range is:
R: [0, 4]

Meri is making birdhouses. Each birdhouse uses 58 yard of wood. What is the total length of wood Meri will need to make 12 birdhouses? Drag each of the numbers from the box to complete and solve the equation. Each number will be used once
Meri will need 696 yards of wood to make 12 birdhouses, as each birdhouse requires 58 yards of wood.
Meri is making birdhouses and each birdhouse needs 58 yards of wood. To find out the total length of wood needed for making 12 birdhouses, we can use the formula:
length of wood per birdhouse x number of birdhouses = total length of wood
So, in this case, we can substitute the given values in the formula:
58 yards x 12 birdhouses = 696 yards
This means Meri needs 696 yards of wood to make 12 birdhouses.
This equation works because it uses the concept of the unitary method, where we find the total length of wood by multiplying the number of birdhouses by the length of wood used in each birdhouse, this way we are able to find the total amount of wood needed.

What is not a polynomial class 10?
A variable-containing expression that divides by a variable, contains fractional or negative exponents, or is enclosed in a radical is not a polynomial.
As long as the polynomial is specified over the real numbers, it is possible for it to have negative coefficients, fractional coefficients, or even radical coefficients.
There cannot be a negative exponent in a polynomial. The exponent of a variable in any term of a polynomial must, by definition, be a nonnegative integer, such as 0, 1, 2, 3, 4, etc. The exponents of variables do not contain fractions, decimals, or negative numbers. There cannot be a variable with a fractional exponent in a polynomial.

if the center of a circle is (-5, -8) and contains the point (16, 68) what is the equation ?
Answer:
[tex](x+5)^2+(y+8)^2=6217[/tex]
Step-by-step explanation:
Hi there!
Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex] where the circle is centered at (h,k) and r is the radius
1) Plug the center of the circle into the equation
Center: (-5,-8)
[tex](x-h)^2+(y-k)^2=r^2\\(x-(-5))^2+(y-(-8))^2=r^2\\(x+5)^2+(y+8)^2=r^2[/tex]
2) Determine r²
Plug in the given point (16,68)
[tex](x+5)^2+(y+8)^2=r^2\\(16+5)^2+(68+8)^2=r^2\\(21)^2+(76)^2=r^2\\441+5776=r^2\\6217=r^2[/tex]
Therefore, r² is equal to 6217. Plug this back into [tex](x+5)^2+(y+8)^2=r^2[/tex]:
[tex](x+5)^2+(y+8)^2=6217[/tex]

the diffrence between the roots of the equation 2x^2-5x+c=0 is 0.25 find c
Answer:
c = 3.09375Step-by-step explanation:
Standard for of quadratic equation:
ax² + bx + c = 0We have
2x² - 5x + c = 0Sum of the roots
x₁ + x₂ = - b/a = -(-5)/2 = 2.5Product of the roots
x₁x₂ = c/a = c / 2We have:
x₁ - x₂ = 0.25The square of the above is:
(x₁ - x₂)² = (x₁ + x₂)² - 4x₁x₂Substitute known values and solve for c:
0.25² = (2.5)² - 4(c/2) 2c = 6.25 - 0.06252c = 6.1875c = 3.09375Answer:
c = 3.09375
Step-by-step explanation:
Factored form of a quadratic equation
[tex]y=a(x-r_1)(x-r_2)[/tex]
where:
a is the leading coefficient[tex]r_1[/tex] and [tex]r_2[/tex] are the rootsGiven quadratic:
[tex]2x^2-5x+c=0[/tex]
Therefore, the leading coefficient is:
[tex]\implies a=2[/tex]
Substitute the value of a into the formula:
[tex]\implies y=2(x-r_1)(x-r_2)[/tex]
Expand:
[tex]\implies y=2x^2-(2r_2+2r_1)x+2r_1r_2[/tex]
Compare the coefficients of x:
[tex]\implies -(2r_2+2r_1)=-5[/tex]
[tex]\implies 2r_2+2r_1=5[/tex]
[tex]\implies r_2+r_1=2.5[/tex]
If the difference between the roots is 0.25 then:
[tex]\implies r_2-r_1=0.25[/tex]
Add the two root equations to eliminate r₁:
[tex]\implies 2r_2=2.75[/tex]
[tex]\implies r_2=1.375[/tex]
Substitute the found value of r₂ into one of the root equations and solve for r₁:
[tex]\implies 1.375-r_1=0.25[/tex]
[tex]\implies r_1=1.375-0.25[/tex]
[tex]\implies r_1=1.125[/tex]
As c = 2r₁r₂ then:
[tex]\implies c=2(1.125)(1.375)[/tex]
[tex]\implies c=3.09375[/tex]

The graphs of lines f an g are shown on the grid. Write a system of equations to represent this graph.
The Equation of line F is y= -9/2x + 59/2.
The Equation of line G is y = 1/10 x .
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
For Line F:
slope = -9 /2
and, Equation of line F as
y - (-2) = -9/2 (x -(7))
y + 2= -9/2( x- 7)
y = -9/2x + 63/2 -2
y= -9/2x + 59/2
For Line G:
Slope = (0 -(1))/ ( 0-(10))
slope = 1/10

Examples of negation are ,
The negation of P is ∼P.The negation of A ^ B^ C is ∼( A ^ B ^ C ).The negation of A is ∼( A ).The negation of Y ^ VB is ∼( Y ^ VB ).The negation of 6 ^ 7is ∼( 6 ^ 7).Logical operations are performed to check the trueness of an expression.
These are generally Boolean expressions or algebraic functions.
A negation of a basic assertion is made by inserting the word "not" into the original statement. The truth value of the negation will always be the inverse of the truth value of the original assertion.
