ใบงานที่ 4Roman PadukaThis document contains an assignment with 4 problems to find the domain and range of different mathematical relationships. The student is asked to write out the domain and range for relationships involving functions of the form y=f(x) where f(x) is a quadratic or linear expression. The student is also asked to determine domain and range by examining the graphs of 2 of the relationships.
ใบงานที่ 3Roman PadukaThe document contains 7 relations and asks the student to find the domain and range of each relation. It provides a series of ordered pairs for the first relation and formulas defining the relationships between x and y for the remaining relations. The student is expected to analyze each relation and determine the set of valid inputs (domain) and outputs (range) for each one.
