Company a rents copiers for a monthly charge of $360 plus 12 cents per copy. company b rents copiers for a monthly charge of $720 plus 6 cents per copy. what is the number of copies above which company a's charges are the higher of the two?

600 or more copies

Step-by-step explanation:

Company A: y = 0.12x + 360

Company B: y = 0.06x + 720

Company A > Company B:

 0.12x + 360 > 0.06x + 720

-0.06x            -0.06x          

 0.06x + 360 >             720  

            -360             -360  

 0.06x           >             360

÷0.06                        ÷0.06

         x          >             600

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
