This bundle contains 9 worksheets on Functions.Worksheet 1: Finding domain and range from graphsStandard. We have determined that the set of solutions to \(y = |x| 2\) is a function; therefore, using function notation we can write: \(\begin{aligned} y & = | x | - 2 \\ \color{Cerulean}{\downarrow} & \\ f ( x ) & = | x | - 2 \end{aligned}\). Given values for x in the domain, we can quickly calculate the corresponding values in the range. Algebra 2 relations and functions worksheet answers can be a useful tool for these scholars.
