Lesson 4-4 Page 295 Linear Functions

Understand how to use tables and graphs to represent functions.

Reminders: Functions can be represented as tables, graphs and equations. Equations can be written as functions; y = 3x + 2 and be written as the function ƒ(x) = 3x +2. To graph a function, make a function table and graph the ordered pairs (x, y).

Try this: p. 296 Step 1: Make a tableStep 2: Graph the ordered pairs xy10 – 2x(x, y)

Graph the function p. 297

Linear function Linear function – a function in which the graph of the solutions is a straight line. Continuous function (data) Continuous function (data) - a function in which there is no space between the data values. Graphs of continuous data are solid lines. Discrete function (data) Discrete function (data) – a function in which there is space between data values. Graphs of discrete data are are represented by dots. p. 298
