Answer:

y = 3(x – 2)² – 1

Step-by-step explanation:

Standard form: y = 3x² – 12x + 11

To convert to vertex form:

y = 3x² – 12x + 11

y = 3(x² – 4x) + 11

y = 3(x² – 4x + 4) + 11 – 12

y = 3(x – 2)² + 11 – 12

y = 3(x – 2)² – 1

Answer:

(x, y) → (-∞, -∞), (+∞, +∞)

Step-by-step explanation:

The expression is of odd degree with a positive leading coefficient. It will have a generally upward slope (/). That is, the sign of f(x) will match the sign of x for large-magnitude values of x:

x → -∞, f(x) → -∞

x → ∞, f(x) → ∞
