Document Summary

1. 1 functions and their representations notes: sterling. Functions are relations between a set of inputs (x-values) and a set of outputs (y-values). Domains are general sets of all of the x-coordinates, which are the rst half of the elements of any ordered pair. Ranges are general sets of all of the y-coordinates, which are the second half of the elements of any ordered pair. The variable x since it can be assigned any number(s) from the given domain. The variable y since its own value is depending on x. This method occurs when you are given the function itself like f (x) = 2x + 5. This method occurs when you are describing the function in words like [ ve plus twice the original value]. This method (best) occurs when you are creating a table with some of the function"s points. This method occurs when you graph the given function.
