Is it a Linear function

Step #1: Fill in the blanks and record on your "Is this a linear function" worksheet.

A __________________ is a pairing of each number in a given set with exactly one number in another set. A function can be represented by a rule, a table or a graph.

A _______________ function is a function whose graph is a line or a part of a line.

Step #2: Look at the graphs on your "Is this a linear function" worksheet and write whether each graph is linear or non-linear.

Step #3: Use this online graphing calculator to graph the equations on your "Is this a linear function" worksheet. Record if each equation is linear or non-linear.

**Note - see the directions on your worksheet so you know how to enter the equation and graph it!!!!!!!!!!!!!!

Step #4: Record what type of equations are linear and what type of equations are non-linear. Do you notice what type of equations when graphed are linear and what type of equations when graphed are non-linear? If so, describe what you see.

Step #5: Graph the ordered pairs in the tables on "Is this a linear function" worksheet and label which graphs are linear functions, non-linear functions, and are not functions.


Step #6: What do you observe about the the tables whose graphs are linear functions, non-linear functions, and are not functions.

Step #7: Predict whether the final table's graphs is a linear function, non-linear function, and are not function

Step #8: Bravo!! Now, please start your homework:-)
