Given

Required
The polynomial function
If a function has a, b and c as its zeros, the function is:

So, we have:


Open the inner brackets

Expand the difference of two squares

Expand

<em>g </em>= gallons.
50 ÷ 4 = g ; which this would then show us that if we were to divide 50 by 4, this would then give us a total of 12.5 which this would show us that would be the amount that he has putted in his truck.
Answer:
y = 3 and y = x + 3
Step-by-step explanation:
The equation y = 3 whose graph is a line parallel to x-axis can be a part of the system.
Consider the equation y = x + 3.
Substitute (0, 3).
3 = 0 + 3
So, (0, 3) lies on y = x + 3 and this can also be a part of the system.
