What is the frequency of the function y = 3sin2x

a. 2/3

b. 3

c. 2

d. None of the above.

d. None of the above.

Step-by-step explanation:

The period is the change in x required to make a change of 2π in the argument to the sine function:

2x = 2π

x = π

The frequency is the reciprocal of the period, so is 1/π. There are no matching answer choices.
