which of these pair of functions are inverse functions?

Option B and C are correct.

Step-by-step explanation:

Inverse function: If both the domain and the range are R for a function f(x), and if f(x) has an inverse g(x) then:

for every x∈R.

Let and

Use logarithmic rules:

then, by definition;

=

Similarly;

for and

then, by definition;

=

Similarly,

g(f(x)) = x

Therefore, the only option B and C are correct. As the pairs of functions are inverse function.
