Functions Domain, Range, Linear Nonlinear

Which relation describes a function? What makes it a function?

• {(-2,3),(-2,5),(-6,7)} Each member of the range is unique.

• {(2,3),(3,3),(3,4)} Each member of the domain and range is positive.

• {(2,3),(3,3),(3,4)} Each member of the domain and range is a real number.

• {(-2,3),(-3,3),(-4,3)} Each member of the domain is assigned exactly one member of the range.
