area bounded by two curves
Ive found the antiderivative to the two functions and im at the last part, where you have to find the total area. This is what it looks like so far...
[ -(x^3)/3 -(x^2)/2 +2x ] theres a small 1 at the top of the last square bracket and a small -2 at the bottom (interval of [-1,2])
Which numbers do I sub in to get the final answer??
I keep thinking its just the first one, but my answer keeps coming out wrong. I keep getting 7/6, but my textbook says the final answer is 9/2.
Where am I messing up?
