Question

What is the average rate of change of the function f(x) = 2(3)^x from x = 2 to x = 4?

Answer 1

72

Explanation:

The way to find the average rate of change between two points is to divide
`(f(a)-f(b))/(a-b)`.
1.) We plug the points into the formula. If you plug them in, you get
`(2(3)^4-2(3)^2)/(4-2)`.
2.) Simplify. If we simplify, we get 3^4-3^2=72

Answer 2

Explanation:

72
