Did students may have difficulty with slope or y-intercept. Now we can pick some numbers to the left and to the right of zero. Then, I will give them time to produce graphs on their own. I would suggest using equal amounts of numbers that are of the same increment. Did students accurately plot open and a closed circles on the plot.

I suggest using the x-coordinate of the vertex,which is as the middle value of all x-values in the table. Did students restrict the domain appropriately or did they extend a graph s outside of its domain?

For this activity the table partners are grouped homogeneously. Did students incorrectly use function notation.

Students should realize that f x is equivalent to y. Errands and Piecewise functions. This is the most basic form of an absolute value function. Warm up piecewise functions 2.

The video below contains is an example of how I might do this with my students: While my students are working I am walk around the room monitoring their progress. This allows us to identify the correct values of m, b, and c which we will use to substitute into the formula.

Then evaluate each value of x into the function to get the corresponding values of y in the table. Then, students are asked to determine the value s of x that corresponds to a given output from a function. Notice that the graph has a low point determined by the middle x-value which is the x-coordinate of the vertex itself, i.

Again, the best way to illustrate this simple idea is through the use of examples! This may work at times, but this idea is not so reliable. Student two wrote two equations horizontally that were correct. If you get it right, you should have something similar below.

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. Earlier, I had demonstrated how to read a function definition and graph a Piecewise Function.

My students have worked with function notation before this lesson. I hope you start realizing that the first step is to always express the given absolute value function in standard form.

In the video below, I demonstrate the strategy I use to teach graphing piecewise functions: Again, emphasizing Math Practice six and the importance of writing function notation correctly.

Plotting the points in the xy-axis, You might also be interested in: Evaluate all values of x into the function to get the corresponding y-values. Look for and express regularity in repeated reasoning.Page 1 of 2 Absolute Value Functions To graph an absolute value function you may find it helpful to plot the vertex and one other point.

Use symmetry to plot a third point and then complete the graph. Math 2 Support Name _____ Absolute Value as Piecewise Functions (Algebraic) Worksheet Rewrite each Absolute Value Function as a Piecewise function. UNIT 3 Absolute Value and Piecewise Functions NAME:_____ DATE:_____ ALGEBRA SKILLZ!

Piecewise Deﬁned Functions Absolute value The most important piecewise deﬁned function in calculus is the absolute value function that is deﬁned by |x| = Another interpretation of the absolute value function, and the one that’s most important for calculus, is that the absolute value of a number is the.
