Answer:
B. P(x) = 0
Step-by-step explanation:
Constant functions are functions where every value of x will yield to the same value. In this case, P(x) = 0 is a constant function because no matter what value of x is, P(x) will always be equal to 0. Constant functions will be easily spotted since the function [P(x)] is equal to an expression that does not include the variable x (in this case 0).
I hope this helps.
