Question

calcule os pontos de cada funçao e preencha as tabelas :

Answer 1

Explicação passo-a-passo:

Tabela f(x)

=>F(-3)

$f( - 3) = 5( - 3) {}^{2} + 2( - 3) + 1$

$f( - 3) = 5(9) - 6 + 1$

$f( - 3) = 45 - 6 + 1$

$f( - 3) =\red{ 40}$

=>F(-2)

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

$f( - 2) = 5(4) - 4 + 1$

$f( - 2) = 20 - 4 + 1$

$f( - 2) =\red{ 17}$

=>F(-1)

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

$f( - 1) = 5(1) - 2 + 1$

$f( - 1) = 5 - 2 + 1$

$f( - 1) = \red{4}$

=>F(0)

$f(0) = 5(0) {}^{2} + 2(0) + 1$

$f(0) = 5(0) + 0 + 1$

$f(0) = 0 + 0 + 1$

$f(0) =\red{ 1}$

=>F(1)

$f(1) = 5(1) {}^{2} + 2(1) + 1$

$f(1) = 5(1) + 2 + 1$

$f(1) = 5 + 2 + 1$

$f(1) =\red{ 8}$

=>Tabela g(x)

=>g(-3)

$g( - 3) = 2( - 3) {}^{2} - 2( - 3) - 1$

$g( - 3) = - 2(9) + 6 - 1$

$g( - 3) = - 18 + 6 - 1$

$g( - 3) = \red{- 13}$

=>g(-2)

$g( - 2) = - 2( - 2) {}^{2} - 2( - 2) - 1$

$g( - 2) = - 2(4) + 4 - 1$

$g( - 2) = - 8 + 4 - 1$

$g( - 2) = \red{- 5}$

=>g(-1)

$g( - 1) = - 2( - 1) {}^{2} - 2( - 1) - 1$

$g( - 1) = - 2(1) + 2 - 1$

$g( - 1) = - 2 + 2 - 1$

$g( - 1) = \red{ - 1}$

=>g(0)

$g(0) = - 2(0) {}^{2} - 2(0) - 1$

$g(0) = - 2(0) + 0 - 1$

$g(0) = 0 + 0 - 1$

$g(0) = \red{- 1}$

=>g(1)

$g(1) = - 2(1) {}^{2} - 2(1) - 1$

$g(1) = - 2(1) - 2 - 1$

$g(1) = - 2 - 2 - 1$

$g(1) = \red{ - 5}$
