Answer:
- {y | –5 < y < - 1}
Explanation:
The graphed function is:
And it is graphed over the domain {x | –8 < x < 8}, which is all the real numbers greater than - 8 and less than 8.
The cube root is a continuous growing function over all the real numbers.
Thus, to find the range you can just substitute the border numbers, -8 and 8, into the function, to find the corresponding y-values.
For x = - 8:
For x = 8
Hence, the range is {y | –5 < y < -1} ← answer
