SOLUTION: what is the domain of following function of x :
{{{ sqrt (3-x) - sqrt (2+x) }}}
Is it -2 <= x <= 3? or am I way off base?

Log On
No, you are spot on. You need the set of numbers that make the first radical defined, namely anything 3 or smaller, and the set of numbers that make the second radical defined, namely anything -2 or larger, and you need the intersection of these two sets because any value in the domain must make both of the square root functions defined.
