1. 30. Graphing & Functions Revision L2Wrapping up our Pure Math revision, we covered Functions. We looked at the basics of Functions, including rule, domain and range. In particular, we focused on Inverse and Composite Functions (do note the mapping technique to find the range of a composite function!). On top of these, we revised applying these ideas on Piecewise/Periodic Functions, and looked at the Identity Function. That's a lot of content for a relatively small chapter, so do keep this perspective in mind as you practice Functions ;) The remaining pages in Secrets Enclosed regarding Inequalities will be uploaded in the coming days, stay tuned.
