So the graph of x = –1 becomes a vertical asymptote. Second, find whether any horizontal asymptotes exist. To do this, solve the equation for x and see whether any values for y would make the new equation undefined. It may not always be easy to solve a rational function for x. ...
The value of x that makes the denominator zero is the point of discontinuity. • Evaluate Rational Functions just like you would any other function. Finding f(4) simply means plug 4 in for x. • When you are looking for x and you know f(x) = some # then you replace the f(x)...
Graphing rational functions and solving rational inequalities without a calculatorjoyce, peter
As long as you do each of these steps, you'll be in good shape to do the plotting (Step 6) and the graphing (Step 7). Once you get the swing of things, rational functions are actually fairly simple to graph. Let's work through a few examples....

Purplemath When you're graphing rational functions, take the time to label your asymptotes and intercepts. Plot enough points for you to feel confident in how the graphed line goes; plot more where you're unsure, less where you're fine. MathHelp.com...
A rational function is a function which is a fraction where both numerator and denominator are polynomials. That is, a ratio of two polynomials P(x) and Q(x), where the denominator Q(x) is not equal to zero. Before we learn, how to graph rational functions, first we have to be awar...
