Answer:
Step-by-step explanation:
hope this helps. good luck.
You have a function

.
Since the range of the function

is
![[-1,1]](https://tex.z-dn.net/?f=%5B-1%2C1%5D)
you have that

.
Answer: The range of given function is [0,3] and the correct choice is C.
Answer:
V = 12³
Step-by-step explanation:
V = 12 × 12 × 12
= 12³
4 3/5 ≈ 5
1 1/5 ≈ 1
(4 3/5) +(1 1/5)
≈ 5 +1
≈ 6 . . . . . . . . . . . the estimated sum rounded to whole numbers
_____
Additional information:
As a refinement to your estimate, you can estimate the error. The first number is 2/5 less than 5. The second number is 1/5 more than 1, so the errors add up to
.. (2/5) +(-1/5) = 1/5
That is, your "estimate" of 6 is actually too high by 1/5. You can refine that estimated value by subtracting 1/5. 5 4/5 would be a closer "estimate."
