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?
