I remember my high school teacher telling me that when I graph a function, I should always plot the point $(0, 1) $, $(1, 0) $ and the origin, $(0, 0) $. Always graphing the first two makes perfect sense, but plotting the origin seems unnecessary. Isn't it obvious that the origin is where two axes intersect? So, I was wondering, was this requirement from my math teacher a sign of his ODD, or something that is useful down the "math learning road"?
