Please help! I’m in a test rn! If f(x) and g(x) are inverse functions of each other, which of the following statements is true?

White raven [17]

Answer:

D) $(g\cdot f)(x)=x$

Step-by-step explanation:

If two functions $f(x)$ and $g(x)$ are inverse of each other, then the following conditions must be true:

i. $(f\cdot g)(x)=x$

ii. $(g\cdot f)(x)=x$

Therefore, out of the four choices available, only option D matches the condition for inverse function to exist.

Therefore, $(g\cdot f)(x)=x$
