i. p(x) = 2x + 5
p(1) = 2 × 1 + 5 = 2 + 5 = 7
p(10) = 2 × 10 + 5 = 20 + 5 = 25
ii. p(x) = 3x2 + 6x + 1
p(1) = 3 × 12 + 6 x 1 + 1
= 3 + 6 + 1 = 10
p(10) = 3 × 102 + 6 × 10 + 1 = 300 + 60 + 1 = 361
iii. p(x) = 4x3 + 2x2 + 3x + 7
p(1) = 4 × 13 + 2 × 12 + 3 × 1 + 7
= 4 + 2 + 3 + 7 = 16
p(10) = 4 × 103 + 2 × 102 + 3 × 10 + 7
= 4000 + 200 + 30 + 7 = 4237
