I am supposed to figure out what this rational function is by using these clues and I am a little confused. Can someone please explain how I do this?

asymptotes:
horizontal~none
vertical~x=-4
slant~y=x+1

end behavior~ f(x) approaches infinity as x approaches infinity; f(x) approaches negative infinity as x approaches negative infinity

intercepts:
x-intercept~ (-6.275,0) and (1.275,0)
y-intercept~ none

domain~ x does not equal -4

There is no range stated.
