# List all restricted values sqrt(2x-5) ?

Apr 2, 2017

All values of $x$ so that $x < \frac{5}{2}$

#### Explanation:

We are given $\sqrt{2 x - 5}$

As we cannot take square root of a negative number,

the restriction on values of $x$ are given by

$2 x - 5 < 0$

or $2 x < 5$

or $x < \frac{5}{2}$
