i need code.

Area Between Curves (functions of x) My Solutions > Recall the process to find the area between curves by integrating with respect to x 1. Sketch the graphs of the curves 2. Find the points of intersection 3. Integrate the larger (top) function minus the smaller (bottom) function over the desired interval. If the curves intersect between the endpoints, integrate over each subinterval. Use this process to find the area between the graphs of f( x ) = x^3 - 3*x"2 and g(x) = 4 x .
