I'm here dude just thinkin :(

I think the answer is d imaginary

anonymous · Answer

the graph of the function is the point (0,0) to check that just solve for any variable using the quadratic formula and you will see that

anonymous · Answer

since it's only one point , no lines are represented by the graph...

anonymous · Answer

so it will be coincident.
