Is {(-3,3), (-2,2), (1,2), (-3,1), (0,3)} a function??

no its not a fuction, Since

x

=

0

produces

y

=

0

and

y

=

4

, the table does not represent a function.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
