Question

find the axis of symmetry of $y = 3x^2 - 6x + 4$.

Explanation:

Step1: Recall axis of symmetry formula

For quadratic $y=ax^2+bx+c$, axis is $x=-\frac{b}{2a}$

Step2: Identify coefficients

$a=3$, $b=-6$

Step3: Substitute into formula

$x=-\frac{-6}{2\times3}$

Step4: Simplify the expression

$x=\frac{6}{6}=1$

Answer:

$x=1$
