Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

Pranza plotted point a in the coordinate plane below.

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
