Name two points on the graph that show that this relation is not a
function

The vertical line test shows if a graph isn't a function because a graph is a function if a straight vertical line can be drawn through it while only hitting one point.

Knowing this, we can deduct that the two points we need to name are (4,2) and (4,-2)

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
