Question

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

Answer 1

vertex = (2, 1)

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 )
