Question

find the area bounded by graph
y= -x^2 - 2x; y=0 ; -2<=x<=1

Answer 1

This is just the integral of (-x^2 - 2x) - (0) dx from -2 to -1.

If you want to find the area underneath two curves from A to B,
you'd want to integrate the difference of those two curves from A to B.

If you want to find the area between a curve and the x-axis, then that's a special case in which the second function is just 0.

Answer 2

thanks.. I will take a look at it
