Graph the data in the table. Decide whether the graph is linear or nonlinear. Compare the two falling objects. Which one has an increasing speed? Functions can either be classified as ________________ or ___________________. Functions Differences Linear 1. Straight Line Nonlinear 1. Not straight/ curve 2. The output has a constant difference 2. The output does not have a constant rate 3. Constant rate = Slope 3. Does not have the same slope 4. Can be written in slope intercept form 4. Cannot be written in slope intercept form 5. Has a degree of 1 5. Has a degree of more than 1. Has an exponent that is not 1. Linear Quadratic Equations Graphs Roots/Zeros – The x-intercepts of a graph. The x-values where the graph crosses the x-axis. Situation 1 – Does the table represent a linear or nonlinear function? Explain. Cubic Situation 2 – Does the equation represent a linear or nonlinear function? Explain. Situation 3 – Does the graph represent a linear or nonlinear function? Explain. Situation 4 – Determine the roots. The graph of f(x) is shown below. What are the zeros?
