F 505. Understand the concept of a function as having a well-defined output value at each valid input value
F 504. Attend to the difference between a function modeling a situation and the reality of the situation
G 406. Locate points in the coordinate plane
What you'll learn
- State the definition of a function: each valid input value has exactly one output value
- Decide whether a set of ordered pairs, a table, or a mapping diagram represents a function, and name the specific input that breaks it when it does not
- Apply the vertical line test to a graph, and explain why it is the definition rather than a separate rule
- Explain why one input with two outputs violates the definition while two inputs sharing one output does not
- Decide whether a described situation is a function by testing whether one input could yield two outputs
- Distinguish a function that models a situation from the situation itself
