Which inequality represents all the values of x for which the quotient below is defined?

√8x^2 / √2x

A x > = 0

B x> 1

C x>0

D x> - 1

For "less than or equal to" you can use <=

For "greater than or equal to" you can use >=

√ (15 (x-1)) / √ (2x^2)

Value under square root must be ≥ 0

Value in denominator not = 0

15 (x-1) ≥ 0

x-1 ≥ 0

x ≥ 1

2x^2 > 0

x^2 > 0

x ≠ 0

Combining both inequalities, we get:

x ≥ 1
