Answer:

To solve this problem, we can use a system of equations.

We know the quadratic expression has the form

f(t)=at^{2}+bt

Using points (1,12) and (4,0), we can form the following system to find a and b.

12=a+b

0=16a+4b

We need to divide the second equation by -4 and sum both equations

12=a+b\\0=-4a-b

12=-3a\\a=\frac{12}{-3}\\ a=-4

Then, we use this value to find the other variable

12=a+b\\12=-4+b\\b=12+4\\b=16

<h3>Therefore, the quadratic function that models the situation is</h3>

f(t)=-4t^{2} +16t  or  f(t)=-4t(t-4)

According to this expression, after 2 seconds, the height is 16 feet.

f(2)=-4(2)(2-4)=-8(-2)=16
