A b^3
B is x^2
I think unless you need to keep it in the fraction so x^6/x^3
What you must do for this problem is to re-imagine the equation in "vertex form"
Vertex form:

where "h" shifts the graph to the right if "h" is positive" and to the left if "h" is negative. K shifts the graph up and down.


a=1
h=1
k=0
So, your final answer should be:
C) 7g - 3=42
All the other ones give the correct value of g except 7g-3=42 because the value of g is 9.
