Question

determina el valor numérico del polinomio, para el valor indicado.​

Answer 1

Respuesta:

Explicación paso a paso:

a$) P( X ) = - 4x^{3}$

P ( 3 ) = -4 ( 3 $)^{3} = -4 ( 27 ) = -108$

b) $P( X ) = -2 x^{4} + 1 + 3 x^{2}$

$P(-1) = -2 ( -1 )^{4} + 1 + 3 ( -1 )^{2} = -2 (1 ) + 1 + 3 ( 1 ) = -2 + 1 + 3 = 2$

$C) P( X ) = 5 - X$

$P( -2 ) = 5 - ( -2 ) = 5 + 2 = 7$

$d) P ( X ) = - 2 x^{4} + 5 -x$

$P ( -2 ) = -2 ( -2 )^{4} + 5 - ( -2 ) = -2 ( 16 ) + 5 + 2 = -32 + 5 +2 = -25$

e ) P ( a ) = 2a -1

P ( -3 ) = 2 ( -3 ) -1 = -6 -1 = -7

$f ) P ( m ) = - m^{4} + 10 + 5 m^{2} - m$

$P ( 3 ) = - ( 3 )^{4} + 10 + 5 ( 3 )^{2} - 3 = -81 + 10 + 5 ( 9 ) -3 = -81 +10+45-3 = -29$
