Anika [276]

Answer:

-4 ≤ f (\theta) ≤ 4

Step-by-step explanation:

The range of a function is the allowed y-values of the function.

We can simply look at the periodic function below and see that the y-value ranges from a negative 4 to a positive 4. It oscillates betwen -4 and 4. That is the range.

We can say -4 ≤ f (\theta) ≤ 4

Last answer choice is right.

*** <u>NOTE:</u> it is a type, not "0", rather "\theta"
