What is the right-hand limit of as x approaches f(x) = x/x-5 as x approaches 5?

Mathematics

Ber [7]3 years ago

Answer:

+\infty

Step-by-step explanation:

The expression for the right hand limit of f(x) is:

f = \frac{x+\epsilon}{x + \epsilon - 5}

The expression can be simplified with some algebraic handling:

f = \frac{1}{\frac{x+\epsilon-5}{x+\epsilon} }

f = \frac{1}{1-\frac{5}{x+\epsilon} }

Let be x = 5, as \epsilon is approaching zero, f is positive and becomes bigger, diverging to +\infty.
