Aball is thrown into the air from the edge of a 48 foot cliff so that it eventually lands on the ground. the graph below shows the height, y, of the ball from the ground after x seconds. for which interval is the ball’s height always decreasing? a. 48 b.0 c.2.5 d.146

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
