Which inequality represents all the values of x for which the quotient below is defined?
√8x^2 divided by √2x
a. x> (or equal to)0
b. x> 1
c. x> -1
d. x> 0

So that the ratio is defined:

* The denominator can not be zero
* Being an integer index pair, the filing must be greater or equal to zero.

It is concluded that:

x ≠ 0  ∧  2x ≥  0   
                x ≥0

.:.  x > 0     

R/ alternative d) x>0
