# Write a piecewise function for each graph Some of the issues I will look for in my students' work on this informal assessment are: Here again we are giving definitions that appeal to your geometric intuition. But what we're now going to explore is functions that are defined piece by piece over different intervals and functions like this you'll sometimes view them as a piecewise, or these types of function definitions they might be called a piecewise function definition.

You might want to review Quadratic Inequalities for the second example below: Free graph paper is available. The next interval is from -5 is less than x, which is less than or equal to So let me give myself some space for the three different intervals.

Step Function A step function is a function, whose graph is a set of lines which appear like steps. So we're actually able to fill it in, and then when x is negative one, negative one plus seven is going to be positive six.

Then, let's see, our function f x is going to be equal to, there's three different intervals. This is going to be, what is this. From the graph of f shown below, we can observe that function f can take all real values on - inf0 U 01] which is the range of function f. Domain of Step Piecewise Function is divided into a number of equal intervals and in each interval, the Range is a constant.

So B is going to B. Graph the following Piecewise Functions. So when x is equal to 10, our function is equal to negative six. It jumps up here. The place on the graph, where the function changes from one piece to another piece. I'm Rachel and thank you for learning with me today. Find this trace point, make sure that the Step Size is set to 1, and then find the points on either side of this point. Graphing a Piecewise Function When graphing Piecewise functions, we have to consider each piece and treat it as a separate function. Primary: Write and graph piecewise functions (A Recognize that functions may be defined by different expressions over different intervals of their domains; Students will write and graph the piecewise function for each plan. Students will make a decision on which plan would be the best for three different usage levels. Students will. Math 2 Name: ____ Piecewise Functions Worksheet #2 Part I. Graph each of the following piecewise functions. Identify any points of discontinuity. Start studying Math Analysis Unit 2 Review. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

What happens to the graph when the function is multiplied by a number greater than 1? \$ up to and including 1/2 mile, \$ for each addtional ½ mile increment.

Graph and write the piecewise function for 0 to. a. No plan – Piecewise? Yes or No b. text plan– Piecewise? Yes or No c. text plan– Piecewise? Yes or No d.

Unlimited text plan– Piecewise? Yes or No If you said that No plan and Unlimited plan were NOT piecewise you are wise. Now, write the function rules for each where x is the number of texts and f(x) is the total monthly cost.

a. Note how we draw each function as if it were the only one, and then “erase” the parts that aren’t needed. You may be asked to write a piecewise function, given a graph. Now that we know what piecewise functions are all about, it’s not that bad! 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.
