Question

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

Answer 1

see explanation

Explanation:

`y = x^2 + 2`

we can solve it by using comleting a square

`y = (x - 0)^2 + 2`

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