Linear Ind

What is a linear function?

• Has a constant rate of change (its graph is a straight line)

• Does not have a constant rate of change (its graph is not a straight line

• Has a constant rate of change (its graph is not a straight line)

• Does not have a constant rate of change (its graph is a straight line)

A function that has a constant rate of change

• Linear

• Exponential

• Quadratic
