Step-by-step explanation:
The general rule for the quadratic function is
Use the data from the table:
We get the system of three equations:
From the first equation
then
Add these two equations:
So,
The quadratic function is
The absolute value of a quantity is 5 if that quantity is either 5 or -5.
So, the two solutions are
Now, there is a bit of ambiguity here: we are not told who and are exactly, and yet the value of depends on our choice.
If we choose a = 2 and b = -3, then the value of a-b is 5
If we choose a = -3 and b = 2, then the value of a-b is -5
