Because you can write:
So definitely a zero degree polynomial function.
In my textbook it indelibly states that f(x)=a, where a cannot equal 0, is a zero degree function. How can that be so? Shouldn't it be a first degree polynomial function, because if it weren't, wouldn't a always be zero then?
actually when you have a n-th degree polynomial then it means that the maximum exponent of x in that polynomial is n.so if you have a zero degree polynomial than it means that the maximum exponent of x is 0 which means that your polynomial looks ike this:
and any number to the power of zero is 1 so:
