Compacted Mathematics Grade 8 (with Algebra I): Functions: Interpreting Functions (F-IF)

Understand the concept of a function and use function notation

F-IF.1

Fully covered
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).

F-IF.3

Fully covered
Recognize that sequences are functions whose domain is a subset of the integers.

Interpret functions that arise in applications in terms of the context

F-IF.4

Partially covered
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.

F-IF.5

Fully covered
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.

Analyze functions using different representations

F-IF.7.a

Partially covered
Graph functions (linear and quadratic) and show intercepts, maxima, and minima.
