Question in How-tos
This question demonstrates defining an 'unknown' function $F(x)$ as a custom function so that it can be used in marking.
The definition of $F$ is arbitrary, so care must be taken to ensure it doesn't have more properties, such as evenness, than necessary.

Question in Demos
Find a regression equation.
Now includes a graph of the regression line and another interactive graph gives users the opportunity to move the regression line around. Could be used for allowing users to experiment with what they think the line should be and see how this compares with the calculated line.
Also includes an updated SSE to see how the sum of the squares of the residuals varies with the regression line.
