You can use GP in many ways.

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

Question 1 )

given ,

height of cylinder = 9 cm

diameter of cylinder = 10 cm

$\dashrightarrow \: radius = \frac{10}{5} \: cm \\$

now ,

$Volume \: of \: cylinder = \pi \: r {}^{2} h \\ \\ substitutng \: the \: values \: of \: h \: and \: r \: \\ \\ \dashrightarrow \: \pi \: \times (\frac{10}{2} ) {}^{2} \times 9 \\ \\ \dashrightarrow \: \pi \: \times 25 \times 9 \\ \\ \dashrightarrow \: 225\pi \: cm {}^{3}$

therefore ,

<u>option </u><u>(</u><u>C)</u> is correct.
