Best ResponseYou've already chosen the best response.0Basically they want you to find intervals where \[ 5x2\geq0 \]

Best ResponseYou've already chosen the best response.0so I remember my teacher doind something like (5x2)^1/4 Do I start it like that?

Best ResponseYou've already chosen the best response.0Nah, you really only have to remember that when you have even roots, you can't have negative numbers inside.

Best ResponseYou've already chosen the best response.0Y= ^4root(5x2) Can you clean that up? It makes no sense as written.

Best ResponseYou've already chosen the best response.0its the quad root of 5x2

Best ResponseYou've already chosen the best response.0OK. 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.

Best ResponseYou've already chosen the best response.0Where the function is defined, it's continuous.

Best ResponseYou've already chosen the best response.0so it is defined when x is > or = .4 ?
