SOLUTION: f(x) 0 1 -1 2 ____________________ x 2 3 3 4 A) state the domain B) state the range C) determine whether f(x) is a function

You can put this solution on YOUR website!
f(x) 0 1 -1 2
____________________
x 2 3 3 4
A) state the domain
Domain is the set {2,3,4}
B) state the range
Range is the set {-1,0,1,2}
C) determine whether f(x) is a function
f is not a function because f(3)=1 and f(3)=-1
This contradicts the definition of a function.
