Answer:
rational
Step-by-step explanation:
that is literally the definition of a rational number, just change the part where it says function to number and polynomial functions to number as well.
Step-by-step explanation:
if b+c=0
b=-c
x^b=x^-c
so
1/[2(x^b)+1]
Assuming this is some kind of modular question, maybe mod 17.
since 1+8+9=1, we can say that 8+9=0
therefore, 2+0=x, so x=2
