where is the part of the graph that contains $\displaystyle x = -2$ ?

$\displaystyle \int_0^8 f(x) \, dx = \int_0^4 f(x) \, dx + \int_4^8 f(x) \, dx = 6 + (-4) = 2$

do you understand that a definite integral is nothing more than the signed area between a curve and the x-axis?

if you do not understand what a definite integral means, then you need to do some research to learn.

start here ...
