The points on the graphs represent relations. Classify these relations according to whether or not they are functions.

Answer:
Function Not a function
Graph A Graph A
Graph C Graph D
Step-by-step explanation:
We know that,
A function is a relation, in which every element of the domain has a unique image in the co-domain.
So, from the options we see that,
Graph A - It is a function as every element have unique image
Graph B- It is not a function as 2 has more than one image namely 1 and 2.
Graph C- It is a function as every element have unique image
Graph D - It is not a function as 2 has more than one image namely 1 and -1
So, we get,
Function Not a function
Graph A Graph A
Graph C Graph D
Answer:
Function Not a function
Graph A Graph A
Graph C Graph D
