Graphing Rational Equations Day 2

How do you determine the vertical asymptote(s) of a rational function?

• Calculate the average of the x-intercepts of the function.

• Find the values of x that make the numerator of the function equal to zero.

• Find the values of x that make the denominator of the function equal to zero.

• Look for the x-values where the function is undefined.
