Rational Function from Asymptote and Intercept
A rational function is defined by the equation $$f(x) = \frac{ax+b}{x+1}$$. If the graph of $$y=f(x)$$ has a horizontal asymptote at $$y=2$$ and $$f(0)=-1$$, which of the following defines $$f(x)$$?
A
$$\frac{2*x-1}{x+1}$$
B
$$\frac{3*x-1}{x+1}$$
C
$$\frac{2*x-3}{x+1}$$
D
$$\frac{2*x+1}{x+1}$$
