Enrollment in a school has grown exponentially since the school opened. below is a graph depicting this growth. determine the average rate of change from x = 0 to x = 20.

an exponential graph has time in years on the x axis and enrollments on the y axis. an upward rising curve begins at zero comma thirty and passes through twenty comma eighty.

0.4

2.5

5

30

2.5

Step-by-step explanation:

The average rate of the function f(x) from x=a to x=b is given by:

From the question, the exponential function goes through (0,30) and (20,80).

This implies that f(0)=30 and f(20)=80

Therefore the average rate of change from x = 0 to x = 20 is

The second choice is correct

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

make sure you have version 2.50

try looking in the very back of the book : )
