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.

go and ask your mom to you

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
