Question

For the graphed function f(x) =(2)^x +2 +1. Calculate the average rate of change from x = -1 to x= 0

Answer 1

B. 2.

Explanation:

You can find the average by substituting the given values in the function, then do an arithmetic average with results.

So, for X = - 1 you get f(-1) = 1

For X = 0 you get f(0) = 3

So, the average with 1 and 3 is 2. Because you sum numbers which results 4, and then divided by 2 (the amount of numbers involved in the average).
