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

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
