a) substitute 0 for x in the equation and calculate f(x) (whenever you see x, you can replace x with 0 and solve for f(x) b) substitute 2 for x in the equation and calculate f(x) c) substitute -2 for x in the equation and calculate f(x) d) substitute (a+b) for x in the equation and calculate f(x) e) x = 8 makes the denominator equal to 0
