.plz solve ques no. 3​

Answer 1

Answer:

(c) x

Step-by-step explanation:

$\displaystyle (f\circ f)(x) = f(f(x))\\\\{}\qquad\qquad=(3-f(x)^3)^{1/3}\\\\{}\qquad\qquad=(3 - (3-x^3))^{1/3}\\\\{}\qquad\qquad=(x^3)^{1/3}\\\\{}\qquad\qquad=x$

Answer 2

Answer:

c) f(f(x))=x

Step-by-step explanation:

f(x)=(3-x³)^(1/3)

f(x)³=(3-x³)

3-f(x)³ = 3-(3-x³) =x³

(3-f(x)³)^(1/3) = x

f(f(x)) = x
