For (1) the shaded region lies below the graph of $y= x^3+ x^2- 6x$ and above the graph of $y= 6x$ for x between -4 and 0. Its area is given by
$$\int_{-4}^0 [(x^3+ x^2- 6x)- 6x]dx$$

For (2) the shaded region lies below the graph of $y= -x^4$ and above the graph of $y= x^4- 32$. Those cross where $y= -x^4= x^4- 32$ or $2x^4= 32$ so that $x^4= 16$: x= -2 and x= 2. Its area is given by
$$\int_{-2}^2 [-x^4- (x^4- 32)]dx$$

Fixed the LaTeX in the first paragraph, some of which wasn't displaying.

That should be more than enough "hints" for the OP to solve the homework problems.

Thread locked, thread moved from "Calculus & Analysis" to Homework & Coursework Questions area.
