How would I solve the following problem?
Sketch the region bounded by the graphs of $f(x)=x^2-4x$ and $-3x^2$ and then find the area of the region.
I have made a sketch for this question but what I am not sure how to do is find the area.
I have found the intersections $x=0$ and $x=1$
So I did
But how can an Area be negative?
