Step-by-step explanation:
If a quadratic function is defined as
... (1)
then, the axis of symmetry is

The given parabolic equation is
.... (2)
On comparing (1) and (2), we get

The axis of symmetry of given graph is



Therefore the axis of symmetry of the given graph is x=1 and option 1 is correct.
