Question

Which ordered pairs display y as a function of x? *O (0,0) (1,-1) (1,-2)O (2.2) (3,-2) (4,5)0 (0,2) (0, -1) (7.1)O (1,-1) (2-1) (1.-3)

Answer 1

A function f maps an element from one domain to a unique range of elements, in this case the only ordered pair which satisfies the previous definition is:

O (2.2) (3,-2) (4,5)
