Question

The graph of f (0) = -4 cos 0 is shown below. The range of this function is

Answer 1

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.

*** NOTE: it is a type, not "0", rather "$\theta$"
