# Write absolute value functions as piecewise functions worksheet

Game Reviews About Me Hi there! My name is Sarah Carter. I used to be Sarah Hagan, but I met an amazing guy who also happens to be a math teacher who blogs through this blog and married him in March Let us consider float division first. We consider those in the next section. For a complete listing of the functions available, see http: We begin with the simplest functions. First, we need to consider how to create our own functions. Next, we learn how to express this equation as a new function, which we can call with different values.

Before we get to solving equations, we have a few more details to consider.

Next, we consider evaluating functions on arrays of values. We often need to make functions in our codes to do things. That is why we see the error above. There are a few ways to achieve that. One is to "cast" the input variables to objects that support vectorized operations, such as numpy.

The syntax is lambda var: I think these are hard to read and discourage their use. Here is a typical usage where you have to define a simple function that is passed to another function, e. You might do this so you can integrate the wrapped function, which depends on only a single variable, whereas the original function depends on two variables.

You can create default values for variables, have optional variables and optional keyword variables. In this function f a,ba and b are called positional arguments, and they are required, and must be provided in the same order as the function defines.

If we provide a default value for an argument, then the argument is called a keyword argument, and it becomes optional. You can combine positional arguments and keyword arguments, but positional arguments must come first. Here is an example. In the second call, we define a and n, in the order they are defined in the function. Finally, in the third call, we define a as a positional argument, and n as a keyword argument. If all of the arguments are optional, we can even call the function with no arguments.Python is a basic calculator out of the box.

Here we consider the most basic mathematical operations: addition, subtraction, multiplication, division and exponenetiation. we use the func:print to get the output. using the slope and one point, write the equation of each side of the absolute value function. Discuss the domain of each side.

Use GO #3 to show students the process for writing absolute value functions as piecewise functions. Go through a couple of examples with the students, then have them complete some practice problems or a worksheet.

If you choose to use this resource, you can ask students to write function rules for each of the graphs they create using either absolute value functions or piecewise functions. If students showed mastery on Problem (2), but struggled with Problem (3) during the warm-up, I will use Graphing Absolute Value Functions Example which scaffolds the process of graphing an absolute value function .
