This morning, I ran across several apps designed to meet common core standards. The one I looked at today is Common Core Nuggets: Building Functions (F-BF/3)by Saltire Software. The app covers vertical and horizontal shifts, vertical and horizontal dilation for linear, quadratic, absolute value, exponential, logarithmic, and polynomial functions.
When you click on the transformation you want, it goes to a screen with the appropriate general equation such as f(x) + k. Underneath the graph is a slider bar with a small button at the right hand side that says go. If you click the go button, the linear graph will move up and down until you hit the stop button.
If you want to see how a different function moves with the same
general equation, you click the change function button at the lower left of the graph. The picture to the left shows both the change function button and the slider bar for the horizontal shift. The small red button at the end of the slider bar is the go/stop button.
This is nice seeing so many functions covered in the app. The only problem is that the instructions are a bit thin and I spent quite a bit of time playing with it until I figured out how to work it. I also discovered the software company has this on their website. The best thing is that this is a free app.
