What is the axis of symmetry and vertex for the function f(x) = 3(x - 2)2 + 4? x=

Vertex:

x = 2 and (2, 4 )

Step-by-step explanation:

The equation of a parabola in standard form is

f(x) = 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 + 4 ← is in vertex form

with vertex = (2, 4 )

This is a vertical parabola, opening upwards and is symmetrical about the vertex.

The axis of symmetry is a vertical line with equation x = 2
