The average rate of change for an exponential function grows by equal [blank1] per unit interval.

The average rate of change for an exponential function grows by equal factor per unit interval.

Step-by-step explanation:

The general exponential equation for growth is given by:-

, where

A= initial value

b= Multiplicative growth rate

x = time period

For each value of x, the value of y increases by an equal value of multiplicative factor ( b).

For example: at x=0 ,

at x=1,

at x= 2,

Hence, the average rate of change for an exponential function grows by equal factor per unit interval.

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
