What is the period of the function: f(x) = 2 sin (3x+pi/3) +5

1 answer

To determine the period of the function f(x)=2sin(3x+π3)+5, we focus on the sine function within the expression.

The general form of a sine function is sin(kx), where k is a constant that affects the period of the function. The period P of the sine function is given by the formula:

P=2π|k|

In our function, we have:

f(x)=2sin(3x+π3)+5

Here, the term k corresponds to the coefficient of x in the argument of the sine function, which is 3.

Calculating the period:

P=2π|3|=2π3

Therefore, the period of the function f(x) is

2π3.
