    F-IF.4



    Overarching Skill / Cluster:

    Interpret functions that arise in applications in terms of the context.

    Standard:

    F-IF-4 For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.*

    Key Vocabulary:

    Key features; intercepts, intervals, max/min, symmetry, end behavior, periodicity

    Supporting Vocabulary:

    Function, independent, dependent, increasing/decreasing, positive/negative

    Learning Targets:

    Interpret key features of graphs (i.e. see vocabulary)

    Interpret tables in terms of quantities.

    Sketch graphs showing graphing key features given verbal descriptions.

    Demonstrators:

    Elaine is in the business of repairing home computers. She charges a base fee of $45 per visit and $25 per hour for labor. The total cost c(x) for a home visit and x hours of labor is modeled by the function c(x) = 45 + 25x. Graph the function and describe the contextual meaning of the intercepts.
