Thread: [SOLVED] Area of a Curve

Question:
6a)
Calculate the area bounded by the parabola, y=8-x^2 and y=x^2.

I don't know how to attempt and I don't know how to find the x intercepts.
Answer:
21/1/3.

Thanks.

Any help?

Is the x intercepts +/- 2.8.

Hi AwsomGuy,

you are looking for the area between the 2 curves.



is a parabola with a maximum at the point (0,8).



is a parabola with a minimum at (0,0).

First find the point of intersection





Now integrate

from x=-2 to x=2
