Answer :

The given polynomial is as follows:

2x – 2x3 + 7


(i) Put x = 3 in the given polynomial


= 2 × 3 – 2 × (3)3 + 7


= 6 – 2 × 27 + 7


= 6 -54 + 7


= -41


(ii) Put x = -1 in the given polynomial


= 2 × (-1) – 2 × (-1)3 + 7


= -2 + 2 + 7


= 7


(iii) Put x = 0 in the given polynomial


= 2 × 0 – 2 × (0)3 + 7


= 0 + 0 + 7


= 7
