 Hi and welcome to the session. Let us discuss the following question. If function f from r to r be given by fx is equal to 3 minus x cube whole raise to the power 1 upon 3 then fofx is a x raise to the power 1 upon 3 v x cube cx d 3 minus x cube. We have to choose the correct answer. Let us start the solution. We are given function f from r to r so we can write function f from r to r is given by fx is equal to 3 minus x cube whole raise to the power 1 upon 3. Now we have to find fofx, fofx is equal to f of fx. This is equal to f of 3 minus x cube whole raise to the power 1 upon 3. We know fx is equal to 3 minus x cube whole raise to the power 1 upon 3. Now this is further equal to 3 minus 3 minus x cube whole raise to the power 1 upon 3 whole raise to the power 3 whole raise to the power 1 upon 3 and simplify and begin. 3 minus 3 minus x cube whole raise to the power 1 upon 3. Now this is further equal to 3 minus 3 plus x cube whole raise to the power 1 upon 3. 3 and 3 will get cancelled and we get x raise to the power 3 multiplied by 1 upon 3. 3 and 3 will get cancelled and we get x as our answer. So the correct answer is c. So we can write c is the correct answer. This completes the session. Hope you understood the session. Take care and good bye.
