The equation given to us is in the Standard form
$y = ax^2 + bx + c$ where $a = 1, b = 0 and c = -1$

The Axis of Symmetry is given by the formula $x = -b/(2a)$

$x = -0/(2*1)$

$color (green)( x = 0$ is the Axis of Symmetry of the Parabola with the equation $y=x^2-1$

What is the axis of symmetry of the function y=x^2-1y=x^2-1?
