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

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
