Answer:

  • y

Step-by-step explanation:

The graphed function is:


  • y=\sqrt[3]{x}-3

And it is graphed over the domain –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:


  • y = \sqrt[3]{-8}-3=-\sqrt[3]{8}-3=-2-3=-5

For x = 8


  • y=\sqrt[3]{8}-3=\sqrt[3]{8}-3=2-3=-1

Hence, the range is y ← answer
