Question

Did I do this problem right? (calculus-area of a region)

Answer 1

the intersection points on the graph are (-2,1) and (2,9)

Answer 2

i did: \[\int\limits_{-2}^{9} (x^2+2x+1-(2x+5))dx \]
and I got 605/3. But now I'm starting to think I should have switched the functions. like:\[\int\limits_{-2}^{9} (2x+5)-(x^2+2x+1))dx\]

Answer 3

how did you get those pretty integer intersections?
how did that one function magically appear?

Answer 4

there's a picture of the two graphs and the intersections

Answer 5

oh wait...i made a mistake. hold on.

Answer 6

I'm suppose to ignore that one function?

Answer 7

\[f(x)=x^2+2x+1 \]
\[g(x)= 2x+5\]
