Which equation describes a rational function with x-intercepts at –4 and 2, a vertical asymptote at x = 1 and x = –1, and a horizontal asymptote at y = –3?

Fourth Option

Step-by-step explanation:

Consider the numerator

x + 4 = 0, x = -4

x = -4 becomes the x intercept

x - 2 = 0, x = 2

Like the question says the two intercepts are x = -4 and x = 2

Now consider the denominator, which will help find the vertical asymptote

x^2 - 1. x = +1, x = -1

Like the question says the vertical asymptote is x=1 and x = -1

The horizontal asymptote is right next to the parentheses
