# Q3 W2 Feb 1-Feb 5 Pre-Algebra

Teacher Stephanie Durrance 8th Grade Math (Pre-Algebra) 8th 2 Focus 8: Introduction to Functions
Standard(s) Taught

MAFS.8.F.1.1: Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is a set of ordered pairs consisting of an input and the corresponding output.

MAFS.8.F.2.4: Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.

MAFS.8.F.1.2: Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).

Learning Targets and Learning Criteria

• identify a function from a graph, equation or set of ordered pairs. • explain that a function represents a relationship between an input and an output where the output depends on the input; therefore, there can only be one output for each input.
• determine the initial value/y-intercept from a table, graph, equation, or two points
• identify the properties of a function written in algebraic form (e.g., rate of change, meaning of y-intercept, linear, non-linear). • compare the properties of two functions that are represented differently (e.g., as an equation, in a table, graphically, or a verbal representation).
