Answer:
-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.

d²=9+36
d²=45

Question 4- is 32.25
question 5- is 12.4
question 6 -is 14/17
question 7 - is 10.7
Let the number of knife be x.
Knife = x
Spoon = 2x
forks = 2x
Total = 30
x + 2x + 2x = 30
5x = 30
x = 6
Knife = x = 6
forks = 2x = 12
Spoon = 2x = 12
Answer: There are 12 forks.
