a) E(x)= -3x3 + 5x – 2x2 – (7/3) -------] E(2) =

b) H(x)= 4x – 2x4 + 3x2 – x5 ---------] H(-1)=

c) G(x)= 5x2 – x3 – (2/5)x4 + (3/2)x ---] G(-2)=

d) K(x)= -2x5 + 3x3 + 4x – 8 --------] K(3)=

Answer 1

Explicación paso a paso:

a)   E(x)= -3x3 + 5x – 2x2 – (7/3) -------] E(2)

E(2) = -3(2)³ + 5(2) - 2(2)² = -3.8 + 10 - 2.4 = -24 + 10 - 8 = -22

b) H(x)= 4x – 2x4 + 3x2 – x5 ---------] H(-1)=

H(-1) = 4(-1) -2 $(-1)^{4}$ - $(-1)^{5}$ = -4 - 2 + 1 = - 5

c) G(x)= 5x2 – x3 – (2/5)x4 + (3/2)x ---] G(-2)=

G(-2) = 5(-2)² - (-2)³ - (2/5)$(-2)^{4}$ + 3/2(-2) = 20 -8 -32/5 - 3 =  9 - 32/5 = 45-32 / 5 = 13/5

d) K(x)= -2x5 + 3x3 + 4x – 8 --------] K(3)=

K(3) = -2(3)5 + 3(3)³ + 4(3) - 8 = 486 + 81 + 12 - 8 = 571
