1

Make a mapping diagram for the relation. {(–3, 3), (1, –6), (2, 2), (5, –5)}


4

Graph the given relation or equation and find the domain and range. Then
determine whether the relation or equation is a function. (3.2, 5.2), (–1.8, 5.2),
(–4.8, 3.2), (–4.8, –2.8)
a  Domain: {–4.8, –1.8, 3.2} Range:
{–2.8, 3.2, 5.2} The equation is a function.  c  Domain:
{–4.8, 5.2, 3.2} Range: {–2.8, 3.2, –1.8} The equation is not a
function.  b  Domain: {–2.8, 3.2, 5.2} Range:
{–4.8, –1.8, 3.2} The equation is a function.  d  Domain: {–4.8,
–1.8, 3.2} Range: {–2.8, 3.2, 5.2} The equation is not a
function.
