Given the domain,D={-1,0,1},which equation represents a function?
A:y²=x² B:x²+y²=25 C:y=1/x D:y=﹣x²
1.This problem need you to test out several points such as D for { -1,0,1}.
2.Example,when you plot coordinate points of ( X,Y) such that (1,-1),(2,0),( 3,1) which
answer choice in A,B,C or D would create something that look for like a line graph?
3.When you are able to figure this out,then you found the answer.
