COMBINATIONS OF FUNCTIONS. SUM OF FUNCTIONS suppose f and g are two functions.the sum of these function is a function which's defined as f+g, where(f+g)(x) = f(x)+g(x) Ex1. if f(x) = 2 - x and g(x) = 3x + 2 then the sum of these functions is given by: (f+g)(x)=(2 - x)+(3x + 2) (collecting liketerms) =2x + 4.... DIFFERENCE OF FUNCTIONS suppose f and g are two functions,the difference of these functions is also a function,defined as: f - g,where (f-g)(x) = f(x) - g(x). Ex2. if f(x) = 3x+2 & g(x)=x-4 then the difference of these functions is: (f-g)(x) = (3x+2) - (x-4) (collecting liketerms) =2x - 6.. i'd created this site to gives you some mathematic tips,if you've any questions you're welcome posted: 5 days ago / last action: 5 days ago
