What is the vertex?
(2,0)
(0,-6)
(-2,-8)
(-6,0)

Hi,

The picture you published shows a parabola, if you look at its lowest possible point, that is the vertex, the coordinates are (--2, --8).

Have you understood ?

Green eyes.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
