How to describe and graph a reflection of an absolute value function

The video tutorial covers four types of functions: constant, identity, absolute value, and quadratic. It explains how to identify and graph absolute value functions, including transformations and reflections. The tutorial also discusses how multiplying by negative values affects the graph, leading to reflections over the X and Y axes. Symmetry in absolute value and quadratic functions is highlighted.

What are the four different types of functions discussed in the text?

Explain the characteristics of the absolute value function.

What is the significance of the vertical line test in determining functions?

How does adding or subtracting numbers inside the function affect the graph?

What happens to the graph of a function when you multiply it by -1 inside the function?

Describe the reflection of the absolute value function over the X-axis.

What does it mean for a function to be symmetrical about the Y-axis?
