Question

r(x)=(x+1)/(x(x+4))
what is the end behavior near -1???

Answer 1

It approaches the value 0

Answer 2

how did you get that?

Answer 3

Plug in x = -1, and you get r(-1) = (-1+1)/(-1(-1+4)) = 0/(-3) = 0
Hence as x approaches -1, r(x) approaches 0

Answer 4

Are we talking about limits? I guess he takes the limits as x goes to -1. Plug the -1 into the equations then u get zero

Answer 5

i hope you can help me figure this out. in the book it shows this r(x)≈ -1/3(x+1) after plugging in the -1. Any idea how they got that?

Answer 6

No idea....
