Question

US
y= 2x2- 6x+ 2?
What is the axis of symmetry for the graph of a=​

Answer 1

Axis of symmetry is
`x=1.5`.

Explanation:

Given equation is
`y=2x^2-6x+2`.

Now we need to find about what is the axis of symmetry of the given function.

So compare it with
`y=ax^2+bx+c`, we get:

a=2, b=-6, c=2

Axis of symmetry is given by the formula

`x=-(b)/(2a)`

`x=-(-6)/(2(2))`

`x=(3)/(2)`

`x=1.5`

Hence final answer is given by:

Axis of symmetry is
`x=1.5`.
