Question

Set up the integral to find the area between the two curves y=11-7x-x^2 and y=1-4x.

Answer 1

hey dolphin

Answer 2

integrate top curve minus bottom curve dx

Answer 3

looks like top curve is y = 11 - 7x - x^2 , and bottom is 1-4x, better check that

Answer 4

Thanks cantorset. That's what I thought. I found the limits are from -5 to 2 Should I integrate from -5 to 2 or split it between -5 to 0 and 0 to +2?

Answer 5

let me check

Answer 6

solve 1-4x = 11 - 7x x^2

Answer 7

yes, I solved and found x=-5 and x=+2

Answer 8

yes

Answer 9

343/6

Answer 10

thats the area

Answer 11

Thanks
