You said you tried plugging in some points from the graph in these equations? What points did you choose?

anonymous · Answer

Oh that was for a different equation. This one is a new one.

heisenberg · Answer

Ah, well same method should work. There are two points that are very easy to spot here: the "zeros" of the graph: (1,0) and (5,0)

do you see that?

anonymous · Answer

Not exactly.. :/ I don't get this one.

heisenberg · Answer

So can you tell me any point on that graph? A point is an x and y coordinate.

anonymous · Answer

1 and 3? I don't know. :(

heisenberg · Answer

A point looks like this: (x, y).

These numbers correspond to points on graphs. Do you see how (1,0) lies on that graph? Do you see how (0,0) does not?

anonymous · Answer

Yeah I suppose.
