Answer :
(i) We have,
Now,
Put x = 0
p(0) = 5 - 4(0) + 2(0)2
= 5 - 4(0) + 2(0)
= 5 – 0 + 0
= 5
Hence,
P(0) = 5
(ii) We have,
Now,
Put x = 3
p(3) = 5 - 4(3) + 2(3)2
= 5 - 4(3) + 2(9)
= 5 – 12 + 18
= 11
Hence,
P (3) = 11
(iii) We have,
Now,
Put x = -2
= 5 - 4(-2) + 2(4)
= 5 + 8 + 8
= 21
Hence,
P (-2) = 21
