The function t = square root h/16 describes the time, t, takes for an object to fall in a vacuum from a given height, h. What is the domain of this function?

Domain of a Function.
Given the function
[tex]t=\sqrt[]{\frac{h}{16}}[/tex]Clearly, we can see that the function only has a real value when h is zero or greater than zero.
Hence,
The correct answer is option C
[tex]h\ge0[/tex]
