Graph piecewise functions with a hole

The video tutorial explains how to graph piecewise functions, focusing on Y = 1/2 X squared and Y = -1. It covers vertical compression, identifying a hole at X=2, and graphing a horizontal line for Y = -1. The tutorial also discusses discontinuities and different domains for the functions.

What is the effect of the coefficient 1/2 in the function Y = 1/2 X^2?

Explain how to determine the values of Y for the function Y = 1/2 X^2 using a table of values.

What does it mean when it is stated that the function cannot be graphed for X = 2?

How do you graph the function Y = -1 when X is equal to 2?

What type of discontinuity occurs at X = 2 in the given piecewise function?
