Which form most quickly reveals the vertex? Choose 1
m(x) = -2(x - 6)^2 + 18
m(x) = -2(x - 3)(x -9)
m(x) = -2x^2 +24x- 54

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 )
