Unit 9: Formulas and Functions

1. How is a formula represented as a function and described verbally?
3, How is a function evaluated and how can you use the desired value of a function to determine the input?
3. How is a table of values used to graph a function and how can the table be used to determine a formula for the function?

Summative and Formative Assessment

MBA 3A. Explain the concept of a function and use function notation. 3B Interpret functions and expressions for functions that arise in applications in terms of the context and situation they model. 3C Analyze functions using different representations

F.IF.1 A. Understand the concept of a function and use function notation

1. HSF-IF.A.1 Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).

2. HSF-IF.A.2 Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.

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

5. HSF-IF.B.5 Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. For example, if the function h(n) gives the number of person-hours it takes to assemble n engines in a factory, then the positive integers would be an appropriate domain for the function.?
