Question

How do you find the equation of the axis of symmetry of `y = 3x² + 6x + 2`?

Answer 1

The axis of symmetry is `x=-1`.

Explanation:

`y=3x^2+6x+2` is a quadratic formula In the form `ax^2+bx+c`, where `a=3, b=6, and c=2`.

The equation for calculating the axis of symmetry for a quadratic equation is `x=(-b)/(2a)`.

`x=(-6)/(2*3)=`

`x=(-6)/6=-1`

The axis of symmetry is `x=-1`.
