The period of f(x)= ( x 3 )+ ( x 2 ) is

Options

  1. A2
  2. B4
  3. C8
  4. D12

Correct answer

D. 12

Step-by-step solution

Given, f(x)= ( x 3 )+ ( x 2 ) Period of x and x are 2 . aligned Period of f(x) & = Period of [ x 3 + x 2 ] & = Period of x 3 + Period of x 2 = & 2 ( 1 3 ) + 2 ( 1 2 ) = 6 1 + 4 1 = & LCM of (6 , 4 ) LCM of (1,1) = 12 1 =12 aligned
