Substitute the values of x = 1, 2 and 3 in the given function.

So, 
f(1) = 1²-2(1)+3 = ?
f(2) = 2²-2(2)+3 = ?
f(3) = 3²-2(3)+3 = ?

If f(x)=x+1/x , prove that [f(x)]³ = f(x³)+3f(1/x).

Dear Hardik,

The MathBuster forum provides you help to better understand the concepts so that you can solve problems independently. 

I have reviewed the PDF attached by you. That seems to be a practice assignment provided by your tutor. We cannot solve the entire assignment for you. 

However, we can definitely help you understand how to solve these problems. Since you are enrolled in the MathBuster course, it will be a good idea to:
  1. Login to your MathBuster account;
  2. Review the NCERT solutions for this chapter (Watch the videos and read the solutions)
  3. Try this assignment on your own.
If you get stuck in any problem, we are available to help you out.

Cheers
Dr. Atul Nischal
