That's not a function.
Since a vertical line hits the graph more than once, if fails the test. (See graph below)
If it is a function, any vertical line you draw can only hit the graph once.
A correction of "six less than twice the value of x" is

The after 9/4 seconds the football is at its highest point which is 81 feet if Lillian kicks a football. Its height in feet is given by h(t)= -16t²+72t
<h3>What is a parabola?</h3>It is defined as the graph of a quadratic function that has something bowl-shaped.
Making perfect square:
The highest point will be when term (4t-9)² becomes zero
So the highest point = 81 feet, and it takes:
t = 9/4 seconds
Thus, the after 9/4 seconds the football is at its highest point which is 81 feet if Lillian kicks a football. Its height in feet is given by h(t)= -16t²+72t
