Would like to have an explanation for this answer. Answer by MathLover1(20855) (Show Source):
You can put this solution on YOUR website! ...as you can see, the radicand is and if radicand is greater or equal to zero solution will be a real number
so, it will be equal to zero if =>-first solution that is real number, and all solutions that are real number will be if
answer: the values of for which f(x) is a real number
