I thought I was working the problem right but I guess not since I had the wrong answer. Can someone please help.

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the region.

y=3x^2, y=x^2+4

So I graphed the curves and saw the intersections were at -1.414214 and 1.412136 ( I assumed these were my from and to for the integral).

The area of 3x^2 is 5.631984 and the area of x^2+4 is 13.18687.

I also assumed that the part we wanted to know was the area of 3x^2 - the area of x^2+4.

I am not sure of this problem. Can anyone help?
