f(x) = (x^2 + x - 2) / (x^2 - 3x - 4)
Domain is all real numbers except the valus of x for which x^2 - 3x - 4 = 0
(x + 1)(x - 4) = 0
x = -1, x = 4
Domain is all real numbers except x = -1 and x = 4. (-∞, -1) ∪ (-1, 4) ∪ (4, ∞)
Range is all real numbers
x-intercepts are the values of x for which x^2 + x - 2 = 0
(x - 1)(x + 2) = 0
x = 1, x = -2
x-intercepts are x = 1 and x = -2
y-intercept is y = 1/2
It has no Horizontal asymptotes
Vertical asymptotes are x = -1, x = 4
