$\large\color{black}{ \displaystyle \sqrt{11} }$ i just a constant

solomonzelman · Answer

so, when you say for example
f(x) = x - a
that is a polynomial function

solomonzelman · Answer

Polynomial - 
has whole number powers (including a power of zero)

and therefore it is defined for all domain (and not necessarily, but mostly for all range, if the power of x is 0).

solomonzelman · Answer

A non-polynomial will (usually, except for exponential functions like e^x, which is non of your options) will be UNDEFINED for some value.

solomonzelman · Answer

You can look through your options and tell me which function will be defined for any x-value. Or/And which function will not be defined for at least 1 x-value.

can you do that for me please?

solomonzelman · Answer

Am I too abstruse?
