At the shoe store the owner noticed that for every 8 pairs of shoes he says he sells 4 pairs of socks if the pattern continues how many pairs of socks will he sell if he sells 56 pairs of shoes

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

if you was gonna solve for a, a is a   < -12
