PLEASE HELP
Which relation is a function?
A {(8, 1), (4, 1), (0, 1), (-15, 1);
B {(-2, -12), (-2,0), (-2,4), (-2, 11)}
C (-4,-6), (-3, -2), (1, -2), (1, 0);
D ((0, 1), (0, 2), (1, 2), (1,3)}

Step-by-step explanation:

cuz the other answers are incorrect.

answer: no, but if it does it's a obvious pattern.

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
