SBAC Calculators

Basic Calculator
This is the calculator that is embedded into the practice problems released by SBAC. Students can work through the tutorial to learn how to enter fractions, exponents, etc.

Graphing and Regression Calculator
Here you will find the calculator that is embedded more so into the performance tasks.

There will be opportunities to learn more about these calculators soon, as well as class activities.

Piecewise Functions for Trig/Math Analysis

We are about to start functions and transformations in trig/math analysis, so I made some piecewise functions in Desmos to use for the intro.

The above function is named f(x). Below is what I entered to graph the function.

Then we can view transformations of f by typing the transformation on an input line to the left of the graph.

You can show or hide each graph by clicking on the colored circle to the left of the equation. Below is 2f(x).

And f(2x).

Here are the links to the Desmos graphs. Graphs 3 and 4 include questions for students to answer. Hope some of you can use them!

All of these functions were taken from Calculus AB free response questions, hence the link back to the website. I also made a table of values to use for by-hand practice.
