## Homework Statement

Since there is a graph and many things, I will post the link of my question.

http://ibhl1-bccalculus.wikispaces.com/file/view/Solutions+to+optional+HL1+practice+for+final+(Larson+text).pdf

Please scroll down to the last page (page 16) and my question is 6c.

## Homework Equations

g(x)=3+∫(2,x)f(t)dt

## The Attempt at a Solution

Here is what I attempt to do: I try to take the integral of g(x) from 2 to 6 and then divide the solution by 4 to find the average value. However, I need to do a double integration on f(t), which I haven't learn yet. I think my approach is too complicated, so is there another way to do the problem? I also think the answer key provided in the link is wrong, can anybody tell me if it is?
