Question

Finding the critical numbers... I have the problem attached in the comments so you can see the exact thing.

Answer 1

the 1st critical number is

x = 0 thats the value that makes the denominator zero, and is a vertical asymptote...

then the x intercept

let y = 0

so

x + 3 = 0

so x = -3 is an intercept...

and lastly...

y = 0 is a horizontal asymptote except at x = -3



hope it helps
