Question

What is the domain of the function f(x) = square root of (12x-24)

I don't get this concept and I have a ton of these problems-can you please explain how to get it
Thank you

Answer 1

What is true of a square root? You cannot take the square root of a negative number (if you're dealing with real numbers anyway). So for what value of X would 12x-24 be 0? anything below that number would make 12x-24 negative and therefore not in the domain.
