Question

You are given the four points in the plane A = (-4,3), B = (-1,8), C = (1,8), and D = (4,4). The graph of the function f(x) consists of the three line segments AB, BC and CD. Find the integral \displaystyle \int_{-4}^{4} f(x)\,dx by interpreting the integral in terms of sums of areas of elementary figures.

Answer 1

Hi! Can you write the integral one more time? Its a little illegible

I understand an integral of -4 to 4 of f(x)dx, its right?

Answer 2

\[\int\limits_{-4}^{4} f(x)dx \] A=(-4,3) B=(-1,8) C=(1,8) D=(4,4)

Answer 3

I dont understand how to start the problem or how to go about it.

Answer 4

aah right

Answer 5

I think I understood
