Answer is 
Explanation:
When we are asked to arrange the polynomial in descending order of the powers, also if there is more than one variable, then we need to add all the powers of the variables and then arrange them.
So here in the question, we have to arrange in descending order for the powers of variable x, so we will take the highest order of x first and then arrange in the descending order, as follows:

Hoped this helped.

Answer:
ind the absolute value vertex. In this case, the vertex for y=−|x|−2 is (0,−2).
(0,−2)
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Interval Notation:
(−∞,∞)
Set-Builder Notation: {x|x ∈ R}
For each x value, there is one y value. Select few x values from the domain. It would be more useful to select the values so that they are around the x value of the absolute value vertex.
