# Which function is more elementary: Constant function or identity function? [closed]

I am not a mathematics teacher, I just want to know which function is more elementary and is more reasonable to be learnt first:

• Constant function (f(x)=1)
• Identity function (f(x)=x)

Thank you,

• At what level are you teaching? The answer differs if you are introducing graphing to algebra 1 students or the concept of a function with function notation to precalculus students, for example. Oct 26 '21 at 3:08

• @OpalE I don't teach, I want to understand what I should learn myself in the future first. Oct 26 '21 at 9:50
• If you want to decide/know which function you should learn first, does this mean that you are currently unfamiliar with $f(x) = 1$ and $f(x) = x$? Could you please clarify what your learning goals are?
