Students will work with expressions, equations, inequalities, and functions.
Look for and express regularity in repeated reasoning. My students have worked with function notation before this lesson. We begin today's lesson with a review of how to evaluate a function, f x when given values for x.
Then, students are asked to determine the value s of x that corresponds to a given output from a function. In the video below, I demonstrate the strategy I use to teach graphing piecewise functions: Warm up piecewise functions 2.
Then I will ask them to compare results with a table partner. For this activity the table partners are grouped homogeneously.
I find that this helps my students to maintain the opportunity to think on their own, and share ideas with confidence.
While my students are working I am walk around the room monitoring their progress. Here are some examples of my students' work on this task: However writes the equations in slope intercept form, and uses function notation incorrectly by placing f of x equal to an inequality.
Students should realize that f x is equivalent to y. Student two wrote two equations horizontally that were correct.
However, the student did not list the equations vertically next to each domain, and the student also numbered within the function notation. Again, emphasizing Math Practice six and the importance of writing function notation correctly.
Errands and Piecewise functions. I will lead this segment of the lesson so that we can focus on some of the difficulties that students experienced during the first half of today's lesson.
Then, I will give them time to produce graphs on their own. Earlier, I had demonstrated how to read a function definition and graph a Piecewise Function. The video below contains is an example of how I might do this with my students: Graphing Piecewise Functions for Alg 1.
Some of the issues I will look for in my students' work on this informal assessment are: Did students restrict the domain appropriately or did they extend a graph s outside of its domain?
Did students accurately plot open and a closed circles on the plot. Did students may have difficulty with slope or y-intercept. Did students incorrectly use function notation.Play a game of Kahoot! here.

Free piecewise functions calculator - explore piecewise function domain, range, intercepts, extreme points and asymptotes step-by-step. The Text(command allows you to display text on the graph screen, using the small font. It takes three arguments: the row, which can range from 0 to the number of pixels tall the screen is (62 on grayscale, on color) at which you want to display something, the column, which can range from 0 to the number of pixels wide the screen is (94 on grayscale, on color), and whatever it is you.
