The cost of a floral bouquet after a discount is applied is represented by the function below, where x represents the number of
flowers in the bouquet.
F(x) = $2.17x - $10.00
What is the average rate of change over the interval (12.24]?

The average rate of change over the interval is 2.17

Explanation:

Given that the cost of a floral bouquet after a discount is given by the function

We need to determine the average rate of change over the interval

The average rate of change can be determined using the formula,

where and

Substituting the value of a and b in the function, we get,

Hence, substituting these values in the formula, we get,

Simplifying, we get,

Dividing, we have,

Thus, the average rate of change over the interval is 2.17

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
