Question

Dado f(x) 0 3x^2 + 2x + 6, encuentre

f(2)/ f(1)+ f(3)

Answer 1

Respuesta:

41

Explicación paso a paso:

$f(x) = 3x^2 + 2x + 6$

Calculamos f ( 1 )

$f(1) = 3(1)^2 + 2(1) + 6$

$f(1) = 3 + 2 + 6$

$f(1) = 11$

Calculamos f ( 2 )

$f(2) = 3(2)^2 + 2(2) + 6$

$f(2) = 3(4) + 2(2) + 6$

$f(2) = 12 + 4 + 6$

$f(2) =22$

Calculamos f ( 3 )

$f(3) = 3(3)^2 + 2(3) + 6$

$f(3) = 3(9) + 2(3) + 6$

$f(3) = 27 + 6 + 6$

$f(3) = 39$

$Calculamos f(2)/ f(1)$

$f(2)/f(1)=22/11$

$f(2)/f(1)=2$

$Calculamos f(2)/ f(1)+f(3)$

= 2 + 39

= 41
