Independent Variable

• Inputs (Domain)

Dependent Variable

• Outputs (Range)

Functions

is a variable that provides the input values of a function

is a variable that provides the output values of a function

• the values of ‘x’ or independent variable

is a relation that assigns exactly one value in the range to eachvalue of the domain. (No Value in the DOMAIN can be repeated)
