What is the period of the function f(x)= (2+ ^2 x ) ?
Options
- A2
- B2
- 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.
