CPM Homework Help : CALC Problem 5-85

Use your calculator to estimate the shaded area shown between the graphs of $y = 4 − 2(x − 2)^2$ and $y = 2^x$ .

Step 1:

Identify where the functions intersect, as well as which function is 'greater' (has higher $y$ -values) than the other.

Step 2:

Integrate: $\int_{\text{intersection }A}^{\text{intersection }B}[\text{top function}]-[\text{bottom function}]dx$
