(i) p (0)

(ii)p(3)

(iii) p(-2)

(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
