The inverse functions have a property that the composition of two inverse functions always results is x.
From the given options, only the pair given in option B result in the composition equal to x.

This proves, F(x) and G(x) are inverse of each other.
So the answer to this question is Option B
0.4 is multiplying itself a number of times.
0.4 is the base.
The number of equal factors of 0.4 is 5, so the exponent is 5.
0.4^5
Answer:
The answer to your question is 2i
Step-by-step explanation:
![\sqrt[4]{-16}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B-16%7D)
- Get the prime factors of -16
- 16 2
- 8 2
- 4 2
- 2 2
1
16 = 2⁴
- Express the -16 as a power
![\sqrt[4]{-2^{4}} or \sqrt[4]{2^{4}i^{2}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B-2%5E%7B4%7D%7D%20%20or%20%20%20%5Csqrt%5B4%5D%7B2%5E%7B4%7Di%5E%7B2%7D%7D)
Remember that -1 = i²
- Get the fourth root of -16
2i
