Sejam os polinômios P(X)= 3x ao cubo - 4x ao quadrado + x - 5, calcule os valores numéricos para:

A X=1

B X=0

C X=-3

Lista de comentários

maell18 P(x) = 3x³ - 4x² + x - 5

A)

p(1) = 3.(1³) - 4.(1²) + 1 - 5
p(1) = 3.1 - 4.1 + 1 - 5
p(1) = 3 - 4 + 1 - 5
p(1) = - 5

B)

p(0) = 3.0³ - 4.0² + 0 - 5
p(0) = 3.0 - 4.0 + 0 - 5
p(0) = 0 - 0 + 0 - 5
p(0) = - 5

C)

p(- 3) = 3.(- 3)³ - 4.(- 3)² + (- 3) - 5
p(- 3) = 3.(- 27) - 4.9 - 3 - 5
p(- 3) = - 81 - 36 - 3 - 5
p(- 3) = - 125
