# Wk2 Q4 Online Learning Apr 6-Apr 10 Algebra 1 Teacher Stephanie Durrance Algebra I Honors 7th/8th 2 Unit 10: Summary of Functions
Standard(s) Taught
 MAFS.912.F-IF.3.9: Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions) MAFS.912.F-LE.1.1: Distinguish between situations that can be modeled with linear functions and with exponential functions.

MAFS.912.F-LE.1.3: Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, as a quadratic or polynomial function.

Learning Targets and Learning Criteria
 • compare key features of two functions when represented in different ways (algebraically, graphically, numerically in tables, or by verbal descriptions). • define linear function and exponential function. • determine whether the real-world context may be represented by a linear function or an exponential function and give the constant rate or the rate of growth or decay. (The function could be represented as a table, a graph, a verbal graph, or symbolically.) • choose an explanation as to why a context may be modeled by a linear function or an exponential function. • demonstrate that a linear function has a constant rate of change and an exponential function has a constant multiplier over equal intervals.

• explain why exponential functions eventually have greater output values than linear or quadratic functions by comparing single functions of each type.
