Q. 74.9( 7 Votes )

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

(i) f(x) =0 (ii) g(x) = 2x3-7x+4

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

(iv) p(x) = 2x2-x+4

(v) q(x) = 4x+3 (vi) r(x) = 3x3+4x2+5x-7

Answer :

Given polynomial,

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


(ii) g(x) = 2x3-7x+4 is a cubic polynomial as degree of the polynomial is 3.


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


(iv) p(x) = 2x2-x+4 is a quadratic polynomial as the degree of polynomial is 2.


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


(vi) r(x) = 3x3+4x2+5x-7 is a cubic polynomial as the degree of polynomial is 3.
