Answer:

Step-by-step explanation:
The standard form of a quadratic is:

To complete the square, the a (leading coefficient) must be 1 and there can only be terms with variables on one side.
The expression given:

follows these rules. Next, we divide the b (linear coefficient) by 2, then square it. Basically:

The b in the expression is -18.


This is the number that is added.
D. x=4 <span>|4 – 6| < 4 = -2 but since anything inside an absolute value sign has to be positive it becomes 2<4.
</span>
The others become:
9<4
4<4
5<4
all of which are not true
Hope that helps
You basically plug in the x values with the given function so the y values are -5,-10,-15,-20
