Answer
(1,-3) is a solution.
Work Step by Step
We are given that $y=\sqrt[3] x-4$.
In order to see whether each ordered pair is a solution of the given equation, we can plug in the ordered pair to the equation.
For (1,-3): $\sqrt[3] 1-4=1-4=-3$
So, (1,-3) is a solution.
For (8,6): $\sqrt[3] 8-4=2-4=-2\ne6$
So, (8,6) is not a solution.
