Polynomial And Rational Function

A function of the form

y = a0 + a1x + a2x2 + ......... + an-1xn-1 + anxn

where ai ε R (I = 0, 1, 2, ........., n) and an ≠ 0 is called a polynomial function of

degree n. The domain of every polynomial function is R.

 

                x  →  P(x)/Q(x) , Q(x)  ≠  0.
