# Identify constant, linear, quadratic and cubic polynomials from the following polynomials:

(i) *f*(*x*) =0 (ii) *g*(*x*) = 2*x*^{3}-7*x*+4

(iii) *h*(*x*) = -3*x*+

(iv) *p*(*x*) = 2*x*^{2}-*x*+4

(v) *q*(*x*) = 4*x*+3 (vi) *r*(*x*) = 3*x*^{3}+4*x*^{2}+5*x*-7

Answer :

Given polynomial,

(i) *f*(*x*) =0 is a constant polynomial as 0 is constant.

(ii) *g*(*x*) = 2*x*^{3}-7*x*+4 is a cubic polynomial as degree of the polynomial is 3.

(iii) *h*(*x*) = -3*x*+ _{is a linear polynomial as the degree of polynomial is 1.}

(iv) *p*(*x*) = 2*x*^{2}-*x*+4 is a quadratic polynomial as the degree of polynomial is 2.

*(v) **q*(*x*) = 4*x*+3 is a linear polynomial as the degree of polynomial is 1.

(vi) *r*(*x*) = 3*x*^{3}+4*x*^{2}+5*x*-7 is a cubic polynomial as the degree of polynomial is 3.
