Find the area of the region enclosed by these graphs and the vertical lines x = −2 and x = 0.

Question

f(x) = x + 3,    g(x) = x² − 9

Answer 1

integral (x+3) dx =x^2/2+3x | evaluate using lower limit = -2, upper limit = 0

integral (x^2-9) dx =x^3/3-9x| evaluate using lower limit = -2, upper limit = 0
