Question

Identify polynomials in the following:
(i) f(x) = 4x³-x²-3x+7
(ii) g(x) = 2x³-3x²+√x - 1
(iii) p(x) = 2/3 x²- 7/4 x +9
(iv) q(x) = 2x²-3x+ 4/x +2
(v) h(x) = x⁴- x³៸² + x-1
(vi) f(x) = 2+ 3/x +4x

Answer 1

Answer:

(i)  It is cubic in x, so, it is cubic polynomial in x variable.

(ii)  Here, exponent of x in√x is not a positive integer, so, it is not a polynomial.

(iii)  It is a quadratic polynomial.

(iv) q(x) = 2x2 − 3x + 4x4x+ 2

Here, exponent of x in 4 / x is not a positive integer. So it is not a polynomial.

(v)  Here, exponent of x in x3/2 is not a positive integer. So, it is not a polynomial.

(vi) Here, exponent of x in 3 / x is not a positive integer, so, it not a polynomial.
