Para determinar el eje de simetría de uan función cuadrática de la forma $f(x)=ax^2+bx+c$, debemos seguir los siguientes pasos:

\n

Paso 1: Determinar los valores de $a$ y $b$ en la función $f(x)=2x^2-8x+12$ (no olvides incluir sus signos)

\n

$a=$[[0]]

\n

$b=$[[1]]

\n

Paso 2: Usar la fórmula del eje de simetría $x=$ $\\Large -\\frac{b}{2a}$, y luego simplificar la fracción obtenida, en caso de ser posible.

\n
