This document contains information about functions and function notation. It defines discrete and continuous data, and provides examples of each. It discusses how to identify functions from graphs and equations, and outlines the function notation f(x). It provides examples of applying the function notation by substituting values into functions. Finally, it presents practice problems identifying functions from graphs and evaluating functions.

- 1. 7
- 2. 2. Simplify: -3(5x - 3) -2(6x - 6) 3. Find the length & width: x P = 68 2x + 10 4. Solve for b: A = ½b • h
- 3. Vocabulary: 1. Discreet Data: Data that has a limited number of values, with space between each value. Usually whole numbers. 2. Continuous Data: Data with values that vary continuously over the graph. Data that is unbroken by space between values. Examples: 1. The number of suitcases lost by an airline: 2. The growth of corn plants: 3. The number of ears of corn harvested.

- 11. Function Notation: f(x)..g(x)..h(x) is a function of Since x can be any number, the f(x) is the output, (the dependent variable), when a number is substituted for x.
