For this case we must indicate an expression equivalent to:
For properties of powers we have to:
So, the above expression can be rewritten as:
Thus, the resulting expression is:

Answer:
Right side towards positive x axis
Step-by-step explanation:
Let us see the basic rule to find the orientation of parabolas.
1. If power if x is 2 and y is 1 , the parabola opens up or down.
2. If the power of y is 2 and that of x is 1 , the parabola opens right or left.
3. If the coefficient of in case 1 is negative it opens downward
4. If the coefficient of in case 2 is negative , it opens left towards negative x axis.
Hence our equation is
here is satisfies the case 2. hence it opens right or left . Also the coefficient of
is positive so it opens up to the right side , that is towards positive x axis.
