8th Grade, CHapter 8
Exponents and Functions
Section 1: In this section, students will learn about compound interest and use patterns of growth to write expressions. Students will analyze the patterns in tables, graphs, and expressions to compare linear and exponential growth.
Section 2: Students will learn new ways to rewrite numbers and expressions involving exponents. They will also learn how to perform operations with these numbers and expressions. Section 3: This section is devoted to special relationships called functions. Students will learn how to distinguish functions from other relationships by examining their graphs and tables.

Expressions and EquationsWork with radical and integer exponents
EE1: Know and apply the properties of integer exponents to generate equivalent numerical expressions.
EE3: Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other.
EE4: Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities.
Functions;Define, evaluate, and compare functions
F1: 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.
F3: Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear.
FunctionsUse functions to model relationships between quantities
F5: Describe qualitatively the functional relationship between two quantities by analyzing a graph. Sketch a graph that exhibits the qualitative features of a function that has been described verbally.
