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 formf(x) = \frac{ax+b}{x+c}.Find an expression for f(x). 

Part (b): Let f be of the formf(x) = \frac{rx+s}{2x+t}.Find an expression for f(x).

a)  We would have [ -4x + 4 ] / [x -3]

Here's the graph........https://www.desmos.com/calculator/ekdhem1jcz

 

b) We would have  [-8x + 8 ] / [2x - 6]

And here's the graph of this one ....https://www.desmos.com/calculator/axjobmjc9s
