1. a student has several boxes of penils in his backpack. each box contains 12 pencils. the student
takes out 1 pencil for himself and gave 3 penils to his friends to use.
which function show the relationship between y, the total number of pencils remaining in his backpack
and x, the number of boxes in his backpack?
a. y = 12x +3
b. y = 128-4
c. y = 12x
d. y = 3x

I think it is A because 12 is the slope and 3 is just b... try y = mx + 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
