Equations and Functions in Your Own Words.
Function is when you take a variable for x and plugged it into the equation and get I result. The function machine takes a number in, knows the equation, and puts out a new number out (y). Or simply what is done to a number to make it another number.
If f(x) =2 then in 4x-4 If f(x) = 3 then 4x-4 If f(x) = 4 then 4(x)-4
4(2)-4 4(3)-4 4 (4) -4
8-4 =4 12-4=8 16-4=12
F(x) =4 F(x) =8 F(x) =12
