Which is not a correct way to describe the function (-3,2), (1,8), (-1,5), (3,11)

  see below

Step-by-step explanation:

The graph appears to have function inputs and outputs reversed. The other representations are correct.

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

i would say true? if the unit was informational and it "refreshed your understanding", then true.
