Answer:
To solve this problem, we can use a system of equations.
We know the quadratic expression has the form

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


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


Then, we use this value to find the other variable

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