see explanation

$y = x^{2} + 2$ $y = x^2 + 2$

we can solve it by using comleting a square

$y = {(x - 0)}^{2} + 2$ $y = (x - 0)^2 + 2$

it means that this equation has a minimum vertex at 2 and it axis of symetry at $x = 0$ $x = 0$ or at $y$ $y$ -axis

What is the axis of symmetry and vertex for the graph y=x2+2y = x^2 + 2 ?
