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

Answer:
True
Step-by-step explanation:
The rate of change is the same as the slope.
Let's find the slope of function 1 using the Rise Over Run rule.
The rise is 2 and run is 1. So your rate of change is 2/1 or 2 for function 1
Function 2 is a y = mx + b equation, the slope is usually "m" or before the x
y = 1/2x + 7
1/2 is your rate of change for function 2
