Which of the following is the best use for the sign chart when graphing rational functions?
A. To determine where the maximum is for the graph of F(x)
B. To determine if the graph of F(x) is straight or curved
C. To determine the slope for the graph of F(x)
D. To determine where the vertical asymptotes are for the graph of
F(x)

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
