Question

classify linear, quadratic and cubic : 3t​

Answer 1

Step-by-step explanation:

Question 5. Classify the following as linear, quadratic and cubic polynomials:

(i) x2 + x (ii) x – x3 (iii) y + y2 + 4 (iv) 1 + x (v) 3t (vi) r2

Solution: (i) x2 + x

Highest power of x is 2 so it is a quadratic polynomials

(ii) x – x3

Highest power of x is 3 so it is cubic polynomial

(iii) y + y2 + 4

Highest power of y is 2 so it is quadratic polynomial

(iv) 1 + x

Highest power of x is 1 so it is linear polynomial

(v) 3t

Highest power of t is 1 so it is linear polynomial

(vi) r2

Highest power of t is 2 so it is quadratic polynomial

(vii) 7x3

Highest power of x is 3 so it is cubic polynomial
