Answer:
x=0
Step-by-step explanation:
The axis of symmetry:
when the equation is 
The given equation is:

To make the a and b values more easily identifiable, we can rewrite it like this:

Now, we can tell that a=1 and b=0. Plug these into the equation
:

Therefore, the equation for the axis of symmetry for the parabola is x=0.
