# Q3W21 Pre-Algebra

Teacher Carol Barnes Pre-Algebra 8th Q3W21 Jan.24-28 Focus 8 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.1.2  Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).

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.

Learning Targets and Learning Criteria
• 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).

•  determine the initial value/y- intercept from a table, graph, equation, or two points
