1. Step-by-step explanation:

   (I) P(x) = 10x – 4x² – 3

   P(0) = 10(0) – 4(0)² – 3 = -3

   P(1) = 10(1) – 4(1)² – 3 = 10 – 4 – 3 = 10 – 7 = 3

   P(-2) = 10(-2) – 4(-2)² – 3 = -20 – 4(4) – 3

   = -20 -16 -3 = -20-19 = -39

   (II) P(y) = ( y + 2 )( y – 2 )

   P(0) = ( 0 + 2 )( 0 – 2 ) = 2 × (-2) = -4

   P(1) = ( 1 + 2 )( 1 – 2 ) = 3(-1) = -3

   P(-2) = ( -2+2 )( -2-2 ) = 0(-4) = 0
