Unit 8- Function (8th Grade)

Unit 8

 

The seventh unit introduces students to relations and functions and defines a function as a relation whose every input corresponds with a single output. From this understanding, students define, evaluate, and compare functions. Functions are described and modeled using a variety of representations, including algebraically, graphically, numerically in tables, and verbally.

Function

Define, evaluate, and compare functions.

MGSE8.F.1 Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.

MGSE8.F.2 Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, give a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.
