Full Question:

The function
y =\sqrt[3]{-x} - 3 is graphed only over the domain of –8 < x < 8. what is the range of the graph?

Answer:


-5 < y < -1

Explanation:

Given

Function:
y =\sqrt[3]{-x} - 3

Range: x

Required

Find the range of the graph

To calculate the range of the graph; we simply substitute the value of x (the domain) at both ends to the given function;

In other words, solve for y when x = -8 and when x = 8

To start with;

When x = -8


y =\sqrt[3]{-x} - 3


y =\sqrt[3]{-(-8)} - 3}


y =\sqrt[3]{8} - 3}


y =2 - 3


y = -1

When x = 8


y =\sqrt[3]{-8} - 3


y =-2 - 3


y = -5

Converting both values of y to inequalities


-5 < y < -1

Hence, the range of the graph is
-5 < y < -1
