The range of the following relation r {(3, −5), (1, 2), (−1, −4), (−1, 2)} is
{−1, 1, 3}
{−5, −4, 2}
{−1, −1, 1, 3}
{−4, −5, 2, 2}

You can rewrite the relation R {(3, −5), (1, 2), (−1, −4), (−1, 2)} as the rule:

The range of relation are all y that are maped to. In your case, the range of relation is the set

correct choice is B.

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
