Which inequality represents all values of x for which the quotient below is defined?
28(x-1) = 8x?
O A. x less than or equal to -1
B. x great than or equal to 1
O C. x> 1
O D. x<-1

You can re-write this quotient this way :

What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))

In other word we must find x so that :

at the end we get

28(x-1) ≥ 0

28x - 28 ≥ 0

28x ≥ 28

x ≥ 1

So the answer is B, x ≥ 1
