Can someone please help me out on this question? I've seen multiple people answer this before but they all don't seem correct.

Question

imreallyasiren · Answer

Given the function f(x) = 4(2)^x, Section A is from x = 1 to x = 2 and Section B is from x = 3 to x = 4.

Part A: Find the average rate of change of each section.
Part B: How many times greater is the average rate of change of Section B than Section A? Explain why one rate of change is greater than the other.

Here is the question

$$f(x)=4(2)^x$$

Plug in.

$$f(1)=4(2)^x$$
$$f(2)=4(2)^x$$
$$f(3)=4(2)^x$$
$$f(4)=4(2)^x$$

Rate of change = Slope = Rise over run = Y-value / x-value

okay so in order it would be 8, 16, 32, and 64?

legomyego180 · Answer

Remember y value over x-value

the first would be 8/1

second 16/2

third 32/3

fourth 64/4

dont forget to simplify
