Question

-

Answer 1

x < -4

Answer 2

that is like the function y = 1/x

there is a vertical line at x=0 in that one where the function can never reach, but gets closer forever

Answer 3

the function you have is shifted sideways (x - a) by amount a

(x + 4) = (x - (-4)). vertical asmptope at x = -4

Answer 4

look at the behavior of the value of the function as you let x move closer to -4 from the left side and the right side

Answer 5

from the left side, the function gets larger and larger as you move towards x=-4

from the right + side, the function becomes smaller and smaller as you move towards x = -4
