Evaluate a piecewise function quick and easy

The video tutorial covers piecewise functions, explaining how to write them using expressions and rules. It discusses evaluating these functions with specific examples, emphasizing the importance of understanding when to apply each rule. The tutorial concludes with a review and application of the concepts in various scenarios.

What is the primary focus when writing piecewise functions?

• Ignoring the rules

• Using only one expression

• Memorizing the expressions

• Understanding the expressions and rules

When evaluating a piecewise function, what should you consider?

• The color of the graph

• The rule that applies to the given value

• The length of the expression

• The number of variables

If X is less than zero, which expression should be used in a piecewise function?

• Any expression

• The expression for X greater than zero

• The expression for X less than zero

• The expression for X equal to zero

What is the result of evaluating the piecewise function when X equals -1?

• 2

• 0

• 1

• -2

How would you evaluate the piecewise function for X equal to 5?

• Use the expression for X less than zero

• Use the expression for X greater than zero

• Use any expression

• Do not evaluate
