Answer:
The vertex of the function is (1.333, 4.667)
Step-by-step explanation:
1. Calculate -b / 2a. This is the x-coordinate of the vertex.
2. simply plug -b / 2a into the equation for x and solve for y.

Calculate -b/2a:


This is equal to 1.33 recurring
Plug 8/6 for x and solve for y:



This is equal to 4.66 reccuring.
