Write F if the given relation is a function write R if not:
1. {(0,2)(2,3)(3,2)(0,0)}
2.{(-1,1)(2,9)(-5,3)(0,0)}
3.{(-6,0)(3,0)(2,0)(1,0)}
4.{(-5,2)(1,3)(-4,2)(1,2)}
5.{(-7,6)(-6,5)(-5,4)(-5,3)}
Answer (1)
Answer:1. R The input 0 maps to both 2 and 0, violating the function rule. 2. F All inputs (-1, 2, -5, 0) have unique outputs. 3. F All inputs (-6, 3, 2, 1) have unique outputs (all 0). 4. R The input 1 maps to both 3 and 2. 5. R The input -5 maps to both 4 and 3.
