What is the vertex of the graph of y = 1/3 (x-9)2 + 5 question 1 options: (9,5) (3,3) (3,5) (-9,5)

ANSWER

The vertex of the graph of

is



EXPLANATION

The vertex form of a parabola is given by



where

is the vertex of the parabola.

The function given to us is


This is already in the vertex form.

When we compare this to the general vertex form, we have,




and



Therefore the vertex of the parabola is



Hence the correct answer is option A.
