Basically they want you to find intervals where \[ 5x2\geq0 \]

Nah, you really only have to remember that when you have even roots, you can't have negative numbers inside.

Y= ^4root(5x2) Can you clean that up? It makes no sense as written.

its the quad root of 5x2

OK. If you take an even root of an expression, the expression has to be greater than or = 0: the even root of a negative number is imaginary. (Odd roots of negatives are fine.) So, as wio said, figure out where the radicand (5x  2) is > or = 0.

Where the function is defined, it's continuous.
