Question 1033903: A function f has horizontal asymptote of y = -4, a vertical asymptote of x = 3, and an x-intercept at (1,0).
Part (a): Let f be of the form
f(x) = (ax+b)/(x+c).
Find an expression for f(x).
Part (b): Let f be of the form
f(x) = (rx+s)/(2x+t).

I will explain just some of it.

Notice degree 1 for both numerator and denominator, equal, so that you can have horizontal asymptote. and similarly .

The given x-intercept indicates and .

You must have denominator equal to zero if x is 3, but x<>3 is the requirement for having given vertical asymptote of x=3.
