Determine whether the function is periodic. if it is periodic, find the period. f(x) = 3 sin 2x + 4 cos 3x

Step-by-step explanation:

We are given that a function

We have to find that given function is periodic or not and if given function is periodic then find the period

We know that if a function is periodic then

We know that sin x and cos x are periodic function with period

Sum of periodic function is also periodic

Hence, given function is periodic function.

Period of sin x=

Then,

Period of cos x is

Hence, period of given function is

8 2/3 is the answer

step-by-step explanation: just use a calculator

i believe the correct answer is b.
