# How do you find the domain and range of sqrtx+5?

Apr 7, 2017

Domain: $x \ge 0$ , Range : $y \ge 5$

#### Explanation:

$y = \sqrt{x} + 5$

Domain: Any real value $\ge 0$ (under root should not be negative).
i.e $x \ge 0$

Range: Any real value $\ge 5$ i.e $y \ge 5$ graph{x^0.5+5 [-45, 45, -22.5, 22.5]} [Ans]
