We have to find which expression represents the amount that was not paid off
Now, we know that, amount that is not paid off = total debt – paid amount


Hence the expression and value of debt amount that is not paid off is found
It is a lot like an equation but instead of and equal sign you put < > ≤ or ≥
For example
X>5 says x is greater than five. Meaning this is only true when x is any number larger than 5 like 7 but not 2.

Answer:
f(-3) = -21
Step-by-step explanation:
To find f(-3), we just need to plug x = -3 into f(x) so:
f(-3) = -4 * (-3)² + 15
= -4 * 9 + 15 = -36 + 15 = -21
