Week 12 – Absolute Value Functions

Absolute Value is a magnitude of real number without regarding to its signs.

The absolute value has the form of y =  |f(x)|, where f(x) is a function.

The x-intercept of the graph of y = f(x) is a critical point also known as point of reflection.

As long as we know the concept of an Absolute Value, it is easy to solve problem solving questions.
