C3 Modulus Function

For A2 Mathematics. This worksheet explores the effect of the modulus function on a quadratic function. The worksheets show the graphs of f(x), |f(x)| and f(|x|) where f(x) = quadratic where the coefficients can be altered. You will need to allow macros to run when using most of the sheets available here. This can be checked by opening Excel and clicking :- Tools Macros Security and choosing Medium or Low security. Also, some sheets require you have Analysis ToolPak installed - this is found by clicking Tools Add ins (you may need the original MS Office disks to do this).
