VA
x=0 or x=-1
HA
as x -> +-infinity, y->1
So that is my work above and I graphed this all too. But.... my question comes here.
When I graph the function f(x) using software, there appears to be no vertical asmptote of x=-1, only x=0 is a VA... This is really strange because I do believe there are two asymptotes..
to find asymptote, set denominator =0 and solve for x.
x^2 + x = 0
x(x+1)=0
x=0 or x=-1
so?? what did I do wrong now?
Note: I did not type the eqtn of the function wrong into graphing software.
