What is the period of the function f(x)= (2+ ^2 x ) ?

Options

  1. A2
  2. B2
  3. C3

Correct answer

B. 2

Step-by-step solution

aligned & f(x+ )= [2+ ^2( +x) ]= [2+ ^2 x ]=f(x) & f(x+2 )= [2+ ^2(2 +x) ]= [2+ ^2 x ]=f(x) & f(x+3 )= [2+ ^2(3 +x) ]= [2+ ^2 x ]=f(x) aligned and minimum value of , 2 and 3 is So, period is.
