TAREA ASIGNADA EL MARTES 05/10

EJERCICIO Nº 1 a)

P8x) = x³ -3 x² + x – 3  

En

x= 3

P(x) = x³ – 3x² +x -3

P (3) = 3³ – 3.3² +3 -3

P (3) = 27 – 27 + 3 -3

P (3) =  0

x = -2

P (x) = x³ – 3x² +x -3

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

P (-2) =  -8 – 12 -2 -3

P (-2) = - 25

x= 0

P(x) = x³ – 3x² +x -3

P (0) = 0³ – 3.0² + 0 - 3

P (0) = 0 – 0 + 0 -3

P (0) =  -3
