College algebra---Interval notation
{x|x>3.83} has to be put in interval notation and then graphed. How do I do this when you don't have it like this. just an example: 2>x>4

anonymous · Answer

in interval notation it would be $(3.83,\infty)$

$$\{x|x>3\}$$ reads 
"the set of all $x$ such that $x$ is greater than 3
