If f(x) = (x^2 - 1)/(x - 1), what is the limit of f(x) as x approaches 1?

Using a table of values, find the limit of f(x) = 1/x as x approaches 0 from the right.

What is the right-sided limit of f(x) = |x|/x as x approaches 0?

Given the graph of f(x), determine the limit of f(x) as x approaches 2 if the graph shows a hole at x = 2 and the y-value approaches 5 from both sides.

Using a table of values, find the limit of f(x) = sqrt(x) as x approaches 4 from the left.
