Determine the vertex of the function f (x) = 3 (x - 2) 2 + 1.

vertex = (2, 1)

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

f (x) = 3 (x - 2) ² + 1 ← is in vertex form

with vertex = (h, k) = (2, 1)
