Question

Find the area between the points of intersection of f(x) = x2 + 3x + 2 and the x-axis

Answer 1

the area under the curve is the integral of the function from one intersection to another

the integral of the function is 2 x + (3 x^2)/2 + x^3/3

now solve it from one intersection to the other.

Answer 2

5.3 sq. units
