Answer:
Step-by-step explanation:
81
=
3
4
and
27
=
3
3
, so this equation can also be written as
3
4
x
=
3
3
(
x
+
2
)
=
3
3
x
+
6
.
Since the bases are now the same, we can equate exponents to get
4
x
=
3
x
+
6
so that
x
=
6
(technically this equating of exponents requires the fact that exponential functions (with base not equal to 1) are one-to-one functions).

Option C is correct
The value of h(f(x)) is, x
Inverse function:
An inverse function that undergoes the other function.
For example: if f(x) is the inverse of g(x) then;
for every x.
As per the statement:
If h(x) is the inverse of f(x).
by definition of inverse:
Therefore, the value of h(f(x)) is, x
