Vocabulary:
Independent Variable
• Inputs (Domain)
Dependent Variable
• Outputs (Range)
is a variable that provides the input values of a function
• the values of ‘x’ or independent variable
is a variable that provides the output values of a function
• the values of ‘y’ or dependent variable
is a relation that assigns exactly one value in the range to each
value of the domain. (No Value in the DOMAIN can be
repeated)
