Please help me answer this question, I dont' know how to find the domain of a question. The question is:

Determine the domain of the function f(x)= -7√(4x-3)

 

[skeeter]

here's an inequality to get you started ...

4x-3 > 0

There are no real square roots of negative numbers.
For what set of values for x is 4x−3 ≥0 ?
That set of values is the domain.
