The correct statement to describe the relationship between any point on ( f(x) ) and ( -f(x) ) is:
If ( (x, y) ) is on the graph of ( f(x) ), then ( (x, -y) ) is on the graph of ( -f(x) ).
This means that if you have a point ( (x, y) ) on the graph of the function ( f(x) ), then the corresponding point on the graph of ( -f(x) ) would be ( (x, -y) ), reflecting the point across the x-axis.
