Typically parking garages, boat rentals, or any place that charges per segment of an hour, are actually using a step function rather than a linear function. There is a fixed price for a certain range of weights and then another fixed price for another range of weights, etc. Worksheets are lesson 3 9 step functions, mathematics ii unit 5 step and piecewise functions part 1, graphing step functions, using the ti 84 plus graphing calculator in middle school, graphing absolute value functions date period, piecewise functions date period, name, graphing piecewise functionsv1. Why do you think it is called a discontinuous function. Ti83 plus, and ti82 graphing calculators, followed by the step by step procedures and examples for the topics of mathematical applications. Mathematics ii unit 5 step and piecewise functions part 1. A cycle of the tangent function has two asymptotes and a zero pointhalfway in. Draw a smooth curve through the three key points, approaching the asymptotes on each side. A step function is discontinuous cannot draw a step function without removing your pencil from your paper.
If youre seeing this message, it means were having trouble loading external resources on our website. Similarly, if the graph goes on forever at the right or up, end with.

Stewart international airport in newburgh, new york charges for parking the way many airports do, by the partial hour. Step functions are piecewise functions that produce graphs that look like stair steps. However, not every rule describes a valid function. Step function characteristics and representing included endpoints on step function graphs are topics covered on the. They reduce any number within a given interval into a single number. For instance, the first line segment is given by the equation y 1 and represents the graph when x is greater than or equal to 0 and less than 1. Graphing the first step in any graphing problem is to draw the graph. Absolute value functions 1 and 2 variables solving evaluating. After the function has been entered, press the graph button, and the calculator will draw the graph for you.
Graph this step function by hand using information from the table. The easiest way to identify the range of other functions, such as root and fraction functions, is to draw the graph of the function using a graphing calculator.
