Step 1. Set the denominator equal to zero.

Step 2. Solve for x. If the equation is a quadratic equation, you must solve for x by factoring, completing the square or applying the quadratic formula.

Step 3. State the equations of the asymptote(s).

Examples Done by Mr. Vizza

Directions: Please calculate the vertical asymptotes of the following functions.

Step 1

x^2+8x=0

Step 2

x(x+8)=0

x=0 & x+8=0

x=0 & x=-8

Step 3

Vertical asymptotes at

x=0 & x=-8

Factor. Both terms have a common factor of x.
