Hi. Can anyone help me with this problem?

Find the area of the regions enclosed by the lines and curves with respect to y.

1. y^2 - 4x = 4 and 4x - y = 16

Thanks.

The graphs intersect at: y = -4, 5.

Solve each equation for x: . x .= .¼y² - 1, . x .= .¼y + 4

. . . . . . . . . . . . .5

The integral is: .∫ [(¼y + 4) - (¼y² - 1)] dy

Soroban, how did you draw that picture, you didn't sit there and type it did you?
