I need help asap. If you could answer both, I'd be grateful. I'll give a thumbs up, thanks. Only a brief explanation is needed.

Consider two functions y] = f(x) and y2 = ch)I and that y. at y; except where they intersect. If these two functions intersect at 21 places, how man).r different integrals do you need to find the total area enclosed by the two curves? Answer: Consider the two functions x] = y2 and x2 = b on the y-interval [-ar a], if a =14.5. What value does b have to be in order for the area between XI and x3 and [-a, a], to equal 80.9? Round your answer to five decimal places. Answer: 21.0422
