What is the range of the function y=3 Sqrt x+8

ValentinkaMS [17]

Answer:

$(-\infty,+\infty)$

Step-by-step explanation:

The given function is

$y=\sqrt[3]{x+8}$

The range refers to the values of y for which x is defined.

We solve for x to obtain;

$y^3=x+8$

$x=y^3-8$

This is a polynomial function in y.

x is defined for all values of y.

Therefore the range is all real numbers.

$(-\infty,+\infty)$

The first choice is correct.
