Question

Solve the inequality |x/(x-1)|<2by interpreting the absolute value function as a distance function.

Answer 1

how do we find the distance between 2 points?

Answer 2

given y1 = a, and y2 = b

d^2 = (a-b)^2

Answer 3

but they seem to just want you to modify the abs function and not the whole thing

|x| = sqrt(x^2)
