13. The following graph describes the height of a football, where the height is measured in meters (m) and time in seconds (s). the What are the values of the zeros or -intercepts? X1=0, x2 =40 and State the value of the vertex. = (20,32)

Note: It is not clear if the graph has been provided or if it is missing from the question.

Assuming the graph has not been provided, we cannot determine anything about the intercepts or vertex of the function.
