Ok so if i was proving that none were present on the horizontal line i would set it equal to 0. Would the proof be y=0 for the derivative equation and 0=2 for the original, which proves it since the two numbers are not equal?

In my opinion that must be sufficient.
To use another attempt you can prove that the graph has a horizontal asymptote y = 0.
