First plug in the equations, then simplify/cancel out terms until you get the answer
Answer:
F(x) and g(x) are not inverse functions.
Step-by-step explanation:
In order to calculate the inverse function of a function, we have to isolate X and after that, we change the variables.
As our function f(x) is a exponentian function, we can apply logarithm with base 10 (log) in both sides in order to isolate X. Remember that log10=1.

Now we change the variables.
F(x) and g(x) are not inverse functions.
