explain whe the function f(x) = x2 - 4/x-2 is not continuous on [0,3] what kind of discontinuity occurs?

use areas to show that integral 0,3 x2-4/x-2 dx = 10.5

use areas to show that integral 0,5 int(x) dx = 10.

how do i do these i really need some help on this my math teacher dosen't really teach.
