Find the area or the region bounded by the curves y = x^3 and y = 9x.

Question

Question options:

1)	0
2)	10.13
3)	40.50
4)	20.25

Answer 1

Sketch it out. The net area is zero, because there are equal areas above and below the x axis!

Answer 2

∫(9x-x³)dx from 0 to 3 = 20.25

4) is the correct answer
