# Q2 W8 Dec 9-13 Algebra I

Teacher Stephanie Durrance Algebra I Honors 7th/8th 8 UNIT 6: Exponential and Radical Functions
Standard(s) Taught
 MAFS.912.F-IF.3.7e: Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases. MAFS.912.F-IF.3.8b: Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function. MAFS.912.F-LE.1.2: Construct exponential functions, including geometric sequences, given a graph, a description of a relationship, or two input-output pairs

MAFS.912.F-LE.2.5: Interpret the parameters in a linear or exponential function in terms of a context.

Learning Targets and Learning Criteria
 • distinguish between exponential functions that model exponential growth and exponential decay and give the rate of growth or decay. • interpret the components of an exponential function in the context of a problem  • use the properties of exponents to rewrite an exponential function to emphasize one of its properties and determine which form of the function is the most appropriate for interpretation for a real-world context. • use the properties of exponents to transform expressions. • use the properties of exponents to interpret expressions for exponential functions in a real-world context. • determine the growth or decay rate and express the rate as a percentage rate of change.
