Homework Statement
Show that f and g are inverse functions (a) analytically and (b) graphically.
f(x) = 5x+1
g(x) = (x-1)/5
Homework Equations
I've got (a), but I'm unsure at how to solve for (b).
The Attempt at a Solution
Here's my (a): [tex]f(g(x)) = 5(x-1/5) + 1 = x[/tex]
How do I solve graphically?
