Question

What is the graph of the function f(x) = the quantity of x squared plus 4 x minus 12, all over x plus 6?

Answer 1

x^2 + 4x -12 = (x+6)(x-2)

so 
  (x+6)(x-2)
---------------- = x - 2
     x + 6

f(x) = x -2

answer is B.

because
if x = -6
then y = -6 - 2 = -8

(-6,-8) is the order pair
