The time will be 2.25 seconds. Then the correct option is D.
What is a function?
A statement, principle, or policy that creates the link between two variables is known as a function.
The function is given below.
h(x) = – 16x² + 100
Where x is the time in seconds and h(x) is the height at x.
Let the height is y feet.
Then the value of y will be
y = 84 – 65
y = 19 feet
Then the time will be
19 = – 16x² + 100
16x² = 100 – 19
16x² = 81
4x = 9
x = 2.25 seconds
Then the correct option is D.
