Question

Find the domain:
f(x) =√(6x-30)

Answer 1

Recall, that to get a real number answer, the argument of our square root has to be nonnegative. That is what we want for our function. So, in this case\[dom(f)=[5,\infty)\]Any number five or bigger makes the argument (radicand) nonnegative.

Answer 2
