Question

Calc Help Please: It's actually High School and I don't know how to change it

Answer 1

I'll help you in one second :)

Answer 2

Have you tried integrating it? (taking the area)?

Answer 3

Since your going backwards, you need to make the first one negative, and anything under the x-axis positive. Therefore, you start with 8 subtract 4, then add 2 for an answer of 6. Thanks for asking a Calc question, I have my AP test this upcoming week :)
