Question

Which inequality represents the all values of x for which the quotient below is defined? sqrt 8x^2/ sqrt 2x
A) x>1
B) x > or equal to 1
C) x>0
D) x>-1
Any help appreciated!

Answer 1

is that sqrt(2x) on the bottom
by the bottom can't be 0 right?
and you want the inside the of square to be positive or 0 but not in this case since the bottom is the sqrt( ) function

so if you want 2x to be positive
then what do you want x to be ?
