Question

What is the axis of symmetry of the graph of `h(x)=(x-1)^2+2`?

Answer 1

`x = 1`

Explanation:

This equation is given in vertex form.
The vertex of the parabola will be at `(1, 2)`

However, the vertex lies on the axis of symmetry which is therefore the vertical line with the same value of the `x`-coordinate

`x = 1`
