For the first of these you'll use the integral from -2 to 1 of sqrt(x) - (x + 4) with respect to x. More generally, integral from a to b of the upper minus the lower function with respect to its input.

for the second one you're going to take the integral from 1 to 3 of x^-1/2 and x^-2. then subtract the smaller value from the larger one.

Just sketch the graphs and find the intersections of the two. The x values of the 2 intersections are your intervals. Then its just integral (with those intervals) of (the higher function - the lower function)
