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

-4 ≤ f (0) ≤ 0

-π ≤ f (0) ≤ 2π

0 ≤ f (0) ≤ 2π

-4 ≤ f (0) ≤ 4

-4 ≤ f () ≤ 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 () ≤ 4

Last answer choice is right.

He has to pay $ 2.76 for the yogurt.

Step-by-step explanation:

Given data

Cost of each ounce = $ 0.24

Vanilla yogurt = 6.5 ounces

Strawberry yogurt = 5 ounces

Total ounces = 6.5 + 5 = 11.5 ounces

Now Total cost of yogurt = 11.5 × 0.24

Now Total cost of yogurt = $ 2.76

Therefore he has to pay $ 2.76 for the  yogurt.
