Question 459922
domain of the square root of 5x-3 
--------------
sqrt(5x-3)
---
Procedure to determine domain:
5x-3 cannot be negative.
---
Solve 5x-3 >= 0
5x >= 3
x >=3/5
-------
Domain: All Real Numbers >= 3/5
-------------------------------------
Look at the graph and you'll see the domain is >= 3/5.
{{{graph(400,300,-10,20,-10,20,sqrt(5x-3))}}}
