Answer:
Step-by-step explanation:
We want to prove algebraically that:
is a parabola.
We use the relations
and
Before we substitute, let us rewrite the equation to get:
Or
Expand :
We now substitute to get:
This means that:
Square:
Expand:
This is a parabola (0,2.5) and turns upside down.
We need to know the definition of the "combined function" h(x). I'm going to guess--by looking at answers--that the function is 
making it
This function is undefined wherever the denominator is equal to 0 (division by zero is undefined). Factor the denominator.
The two values of x that make the denominator 0 are 3 and -3, otherwise written
