Answer: if f(x) is our function and g(x) the inverse, then
f(g(x)) = x
"If f(x) asigns elements from a set I to a set K, then the inverse function traces back the elements from K to the original elements on I"
Step-by-step explanation:
If we have a function f(x) = y that is invertible (f(x) must be biyective)
Then the inverse function g(x) is such that:
g(y) = x
this means that:
g(y) = g(f(x)) = x
and
f(x) = f(g(y)) = y
