Answer:
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.

Answer:
15
Step-by-step explanation:
Let n represent the number of twelvths in 5/4.
Expressed symbolically, this is n/12 = 5/4.
The LCD is 12. Multiply numerator and denominator of 5/4 by 3, obtaining:
n/12 = 15/12. Then n = 15.
There are 15 twelves in 5/4.
3 1/5 x 7 1/4
= (15/5 + 1/5) x (28/4 + 1/4)
= 16/5 x 29/4
= (29x16) / (5x4)
= 464/20
= 116/5
= 20 16/5
