Focus F: Analysis of Rational Functions

Example 3:

• To find the oblique asymptote, you must first find the quotient and remainder.
• The quotient is x - 4 and the remainder is 4. Thus, the function can be rewritten as .
• For large (absolute) values of x, the value of approaches zero.
• The oblique asymptote is given by y = x - 4.
