Algebra ->  Functions -> SOLUTION: The rule of the function f is "add one" and the rule of the function g is "multiply by 5." How can I express these functions algebraically? f(x) = g(x) = (f º g)(x) =       Log On


   



Question 905484: The rule of the function f is "add one" and the rule of the function g is "multiply by 5."
How can I express these functions algebraically?
f(x) =
g(x) =
(f º g)(x) =
(g º f)(x) =
please explain how these are done, I must understand.
Thank you

You can put this solution on YOUR website!
f(x) = x +1 "add one"
g(x) = 5x "multiply by 5."
(f º g)(x) = (5x)+1 Substitute 5x for x in f(x)
(g º f)(x) = 5(x+1) Substitute (x+1) for x in g(x)
