Kate and Mateo are on a hill by a river. Kate throws a stick into the river. Her stick’s path is described by the equation y = –5x^2 + 10x + 9.

Mateo is higher on the hill than Kate. He also throws a stick into the river. The path of his stick is shown in the graph.



In each function, x is the stick's horizontal distance from the hill and y represents its height. Both are measured in feet.

Whose stick reached a higher point above the river?

A. Mateo’s stick reached a higher point.
B. Kate’s stick reached a higher point.
C. The two sticks reached the same height.
