Question

For what values of x is the expression below defined?A.x < 1B.x < 0C.x = 0D.x > 0

Answer 1

`(√(2x^2))/(√(5x))`

As we can see, we have a radical expression and a quotient. Since we can't divide by zero:

x must be different than 0

`x\\e0`

Also, x must be positive since a negative x would result into a negative radicand for the denominator, so:

`x>0`

Answer:

D
