Can someone tell me the exact answer to this question pls and you i will give brainliest

(- 1, 2 ) and ( -1, 0) have the same x-value

for the graph to represent a function there must be only one y- value for each x- coordinate. Here there are 2 so this is not a function

the infinity sign

step-by-step explanation:

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
