Students should realize that f x is equivalent to y. Again, the best way to illustrate this simple idea is through the use of examples!

Here are the graphs, with explanations on how to derive their piecewise equations: Learn these rules, and practice, practice, practice! Errands and Piecewise functions. We generated the rest of the x by finding three numbers to the left and right of the middle value of 2 with an increment of 1.

Note that this piecewise equation is non-continuous.

Write a function that models this situation. And, even better, a site that covers math topics from before kindergarten through high school. This allows us to identify the correct values of m, b, and c which we will use to substitute into the formula.

So, the piecewise function is: You may also be asked to take an absolute value graph and write it as a piecewise function: While my students are working I am walk around the room monitoring their progress. You plan to sell She Love Math t-shirts as a fundraiser.

That costs more than a human haircut at least my haircuts!

Graphing Piecewise Functions for Alg 1. The piecewise function is: For this activity the table partners are grouped homogeneously. Now we can pick some numbers to the left and to the right of zero. In the video below, I demonstrate the strategy I use to teach graphing piecewise functions: To review how to obtain equations from linear graphs, see Obtaining the Equations of a Line, and from quadratics, see Finding a Quadratic Equation from Points or a Graph.

We learned how about Parent Functions and their Transformations here in the Parent Graphs and Transformations section. The video below contains is an example of how I might do this with my students: If you get it right, you should have something similar below.Piecewise Functions WS Evaluate the function for the given value of x.

Match the piecewise function with its graph. Carefully graph each of the following. Identify whether or not he graph is a function.

Then, evaluate the graph at any specified domain value. You may use your calculators to help you graph, but you must sketch it carefully on the grid! MAT Section Worksheet on Piecewise Functions Example 1.

Consider the function f(x) = ˆ x+ 4, if 6 x 3 4 1 3 x, if 3. Practicing our Piecewise (again!) Name_____ Date_____ Evaluate the function for the given value of x.

Match the piecewise function with its graph. Pre-AP Algebra 2 Lesson – Piecewise Functions Objectives: The students will practice answering graphical analysis questions (focus on absolute value questions), including operations with two functions on the same set of axes. The students will be able to graph a piecewise function.

4. Graph the piecewise function and evaluate it at the given values of x. () Evaluate. () 5. Write the piecewise function for the graph. SWBAT describe a piecewise function in their own words, graph it, and write equations modeling the graph.

Big Idea In this lesson we apply function notation to piecewise defined functions and assess students' ability evaluate functions in different forms.
