Discussion:

-2 sqrt(20) - sqrt(125) =

-2 *2 sqrt(5) - sqrt(125)= as 20 = 4* 5

-4sqrt(5)- 5 sqrt(5) = as 125 = 25 *5

(-4 -5) sqrt(5) =

-9 sqrt(5)

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

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 " $\theta$ "
