graphs.

From the hand shaded screenshot shown above right it can be seen that

to find the area we need to split it into two sections, with the boundaries

being -2 and the two intersections.

After finding the first intersection using

Intersection we change into the

HOME view and

store the results into memory variable

We then do the same thing for the second

intersection, storing the result into

We can now calculate the area in the

HOME view, using

for the second. Use to duplicate the first

integral and edit it to adjust the functions and limits.
