Question

How do you graph `y=1/3sqrtx` and what is the domain and range?

Answer 1

x must be a positive number or 0.

Explanation:

If `x=0` y will become `y=0`
If `x=4` y will be `y=2/3`
If `x=25` y will be `y=5/3`

Here is the graph:

graph{(1/3)sqrt(x) [-2, 50, -1, 4]}

The domain: `[0,oo)`
The range: `[0, oo)`
