Question

could someone teach me how to approach these questions.

find the area under the following curves
y=7-x^2, between the values x=-1 and x=2

Answer 1

I assume that it is bounded by the x-axis?

Answer 2

If so, it is the integral of (7 - x^2) dx from 1 to 2

Answer 3

How do you set up the integral?
