## Homework Statement

I should sketch function (x^2 + x -12)/(x-4).

## The Attempt at a Solution

I have problem with first derivative i find it to be (x^2 - 8x +8)/(x-4)^2 with roots at 4 - 2√2, 4 + 2√2, and 4(we lose four because f is not defined at 4). Where at 4 - 2√2 f is at max and at 4 + 2√2 f is at min. But when i plug those two roots in f i find that when x 4 - 2√2 f is = 3.32 and when i plug 4 + 2√2 i find f to be 16.47. How come min is greater then max? Is that even possible?
