D: x=y^2 and x-y=2
Thx you for your answers!!
1) you didn't specify your problem exactly
2) I interchanged x and y, So your figure is basically the same as my region
3) Try
Plot[{x^2, x + 2}, {x, -2, 3}] Integrate[x + 2 - x^2, {x, -1, 2}]
it's wrong, another shape is bounded by these lines. y^2=x and x-y=2
Plot[{x^2, x + 2}, {x, 0, 3}] Integrate[x + 2 - x^2, {x, 0, 2}]
