Essential Understandings

Concrete:

• Use concrete cause and effect examples (e.g., add blue (x) to yellow [f(x)] to get green (y).
• Use distance (y)/time (x) scenarios where movement f(x) is the function of time (e.g., how long does it take to cross the room).
• Use a function box, e.g.,
  
  

• Recognize in an ordered pair that the first number represents the domain (x-value) and the second number represents the range (y-value).
• Understand function notation (e.g., in y = f(x) is another way to write y is f(x) – read f of x).
• Understand x as the input and y as the output (cause and effect).
• Understand that the graph of f is the graph of the equation y = f(x).
