Question

valor polinomio p(x) 3x4- 4x+3 para o valor de x= -1/2

Answer 1

Resposta:

$p(x)=3x^{4} -4x+3 \\\\p(-\frac{1}{2} )=3(-\frac{1}{2} )^{4} -4(-\frac{1}{2} )+3\\\\p(-\frac{1}{2} )= 3.\frac{1}{16} +\frac{4}{2} +3\\\\p(-\frac{1}{2} )= \frac{3}{16} +2+3\\\\p(-\frac{1}{2} )=\frac{3}{16} +5\\\\p(-\frac{1}{2} )= \frac{3}{16} +\frac{5}{1} \\\\p(-\frac{1}{2} )=\frac{3+80}{16} \\\\p(-\frac{1}{2} )=\frac{83}{16}$
