ILL GIVE BRANLIEST given the function f= {(3,1),(4,-2),(1,-1),(-3,4)}
1. determine f(1):
2 for what value of x is f(x)=1:

1.  f(1) = -1

2. for x=3 f(x)=1

Step-by-step explanation:

According to function definition:

 for x=1  f(x)=f(1)=-1   (for first answer)

 for x=3 f(x)=f(3)=1   (for second answer)

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
