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

Apr 18, 2017

x must be a positive number or 0.

#### Explanation:

If $x = 0$ y will become $y = 0$
If $x = 4$ y will be $y = \frac{2}{3}$
If $x = 25$ y will be $y = \frac{5}{3}$

Here is the graph:

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

The domain: $\left[0 , \infty\right)$
The range: $\left[0 , \infty\right)$
