To answer the questions, here are the appropriate responses based on the characteristics of functions and graphs:
A. Which graph(s) are not a function?
Response area: Graph A and B
B. Why are the graph(s) NOT a function?
Response area: Because each input does not have exactly one output
C. Which graph(s) are NOT Linear?
Response area: Graph A and C
D. Which graph(s) have a constant rate of change?
Response area: Graph B
Please adjust the responses based on the specific characteristics of graphs A, B, and C if different than assumed in this explanation.
