Answer:

Step-by-step explanation:
The given expresion is

We want to evaluate this expression for x=2.
We substitute x=2 into the expression.
This means that, we will put 2 wherever we see x in the given expresion.
This will give us:

Answer:
x = 2
Step-by-step explanation:
Since you didn't attach an image of the graph I'll have to do this the long way and use a strategy called "completing the square" to find the vertex. The x-coordinate of the vertex is the axis of symmetry.
x² - 4x + 6
= (x - 2)² - 4 + 6
= (x - 2)² + 2, therefore the vertex is (2, 2) so the axis of symmetry is x = 2.
