Question

Between x = 2 and x = 3, which function has a greater average rate of change than y = 1/ 3 ^-x ?

A) y = 2^x

B) y = 5^x-2

C) y = 1 /4 ^-x

D) y = 2 /3 ^-x

Answer 1

C) Y= 1/4-X

Explanation:

average rate of change =

Δy/Δx

The average rate of changes for each of the functions between 2 and 3 is 4, 48, 9/8 , and 4. The average rate of change of y = 1/3 -x is 18. Therefore the average rate of change that is greater is 48, which is the function y = 1/4 -x

Answer 2
