Question

Find the area under the curve y=5/x^2 between x=-3 and x=-1.

Answer 1

We tend to discourage homework dumps here. If these problems bother you, review your text, and google definte integrals for many discussions and examples.

Always make a sketch of the region. You have learned how to sketch graphs give the functions, so draw a picture. It always helps to define the region.

In this case, the area is assumed to be bounded also by the x-axis.
