Question

What is the axis of symmetry and vertex for the graph `y = 2x^2 - 8x + 10`?

Answer 1

The axis of symmetry is `x=2` and vertex is at `(2,2)`

Explanation:

`y=2x^2-8x+10 = 2(x^2-4x+4)+10-8=2(x- **2** )^2+ **2** The vertex is at`(2,2)`and the axis of symmetry is`x=2# graph{2x^2-8x+10 [-10, 10, -5, 5]}[Ans]

Temporary demonstration of formatting by Tony B

There is a problem with the [ 'double star'2'double star' ]. It messes up the auto formatting if included in non text string. I have tried often to get round this but in the end gave up.What should be written in your mathematical string is:

`y=2x^2-8x+10 = 2(x^2-4x+4)+10-8=2(x- 2 )^2+ 2`
The vertex is at `(2,2)` and the axis of symmetry is `x=2`
