Find the area of the indicated region
f(x)=(4x^2) between(0,2)with 4 equal subintervals (left endpoints)

They are asking you to do an approximate numerical integration, rather than compute the exact area with calculus. The area will be approximated as the sum of the areas of four rectangles.
Compute the values of f(x) at x = 0, 0.5, 1, and 1.5. Add up the values and multiply them by the subinterval width, 0.5.
