4-2 Additional Practice Graphing Rational Functions Answer Key. 1.find the domain of r. Clearly identify all intercepts and asymptotes.

Clearly identify all intercepts and asymptotes. F (x) = −4 x−2 f ( x) = − 4 x − 2 solution. 2.reduce r(x) to lowest terms, if applicable.

Steps For Graphing Rational Functions Suppose Ris A Rational Function.

1.find the domain of r. Graph f(x) = ixi + 2. F (x) = −4 x−2 f ( x) = − 4 x − 2 solution.

Sketch The Graph Of Each Of The Following Functions.

2.reduce r(x) to lowest terms, if applicable. Remember that f(x) is function notation for y, so rewrite the function as y = ixi + 2. Graphing functions there are three steps to graphing a function.
