This week in math we started the unit Relations and Functions. We began the week with some basic review of things like graphs, finding x and y coordinates, vocab and ect. One thing I forgot about was independent and dependent variables which are basically different ways to say x and y. Later in the week we moved on to some newer, more challenging things such as domain and range, finding the x and y intercept, and the differences of functions and relations.
I probably had the most trouble with was finding domain and range. I understood what domain and range was and that there can be infinite values between two relations but I didn’t know how to write it exactly. After some trial and error and looking at Khan academy videos I understood it better and am a lot more confident about writing domain and range.
