Which form most quickly reveals the vertex?

Choose 1 answer:

m (x) = - 2 (x - 6) ^2 + 18

m (x) = - 2 (x - 3) (x - 9)

m (x) = - 2x^2 + 24x - 54

The third one.

first option

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a (x - h) ² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

m (x) = - 2 (x - 6) ² + 18 ← is in vertex form

with vertex = (6, 18)
