If x = 1/2, then x -1/2 = zero. this is the same as = zero

a) 2x-1
b) 2x+1
c) 2x

A) 2X-1

Step-by-step explanation:

X=1/2

X-1/2 will be the same as 1/2-1/2

Which equals zero

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
