# What is the end behavior of the square root function?

The square root function $f \left(x\right) = \sqrt{x}$ has domain $\left[0 , + \infty\right)$ and the end behaviour is

as $x \to 0$ , $f \left(x\right) \to 0$

as $x \to \infty$ , $f \left(x\right) \to \infty$

Note: "end behavior" of a function is referred to the behavior of a function when it reaches towards its extreme points.
