Question

whats 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 a, b values

From $y=3x^2-6x+4$, $a=3$, $b=-6$

Step3: Substitute into formula

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

Step4: Simplify the expression

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

Answer:

x=1
