Question

1. (1,0) Seja o polinômio A(x) = x -x-3. Calcule:
a) A(1):
b) A(0)
c) A-4) =​

Answer 1

Explicação passo-a-passo:

A(1) = 1-1-3

A(1)= -3

B) A(0) = 0-0-3

A(0) = -3

C) A(-4) = -4-(-4)-3

A(-4) = -4 +4 -3

A(-4) = -3

• $\large\boxed{{\sf \large\boxed{{\sf \sf\color{yellow}{}A(x) = x -x-3{}}}{}}}$

a)

$\sf\color{red}{}A(1) = 1 - 1 - 3 \\ \sf\color{red}{}A(1) = 0 - 3 \\ \sf\color{red}{}A(1) = - 3$

b)

$\sf\color{green}{}A(0) = 0 - 0 - 3 \\ \sf\color{green}{}A(0) = 0 - 3 \\ \sf\color{green}{}A(0) = - 3$

c)

$\sf\color{blue}{}A( - 4) = - 4 - ( - 4) - 3 \\ \sf\color{blue}{}A( - 4) = - 4 + 4 - 3 \\ \sf\color{blue}{}A( - 4) = - 3$
