Sagot :
1. p(1) = 3(1)^4 + 16(1)^3 - 10(1)^2 - 9
=3 + 16 - 10 - 9
= 0
p(-3) = 3(-3)^4 + 16(-3)^3 - 10(-3)^2 - 9
=81 - 432 - 90 - 9
= -450
2. p(1) = (1)^3 + 4(1)^2 + 7(1) - 11
= 1 + 4 + 7 - 11
= 1
p(-3) = (-3)^3 + 4(-3)^2 + 7(-3) - 11
= -27 + 36 - 21 - 11
= -23
3. p(1) = (1)^4 - 3(1)^2 - 1
=1 - 3 - 1
= -3
p(-3) = (-3)^4 - 3(-3)^2 - 1
= 81 - 27 - 1
