Question in Demos
The student is shown a plot of a mystery function. They can enter values of $x$ check, within the bounds of the plot.
They're asked to give the formula for the function, and then asked for its value at a very large value of $x$.
A plot of the student's function updates automatically as they type. Adaptive marking is used for the final part to award credit if the student gives the right value for their incorrect function.

Question in How-tos
This question models an experiment: the student must collect some data and enter it at the start of the question, and the expected answers to subsequent parts are marked based on that data.
The student's values of the variables width, depth and height are stored once they move on from the first part.

Question in How-tos
This question models an experiment: the student must collect some data and enter it at the start of the question, and the expected answers to subsequent parts are marked based on that data.
A downside of working this way is that you have to set up the variable replacements on each part of the question. You could avoid this by using explore mode.
