Answer 1

Resposta:

a) -1

b) 1

c) 2

d) 8

e)

$\begin{tabular}{c | l}x & f(x) \\\cline{1-2}0 & -3 \\1 & -1 \\-1 & -5 \\2 & 1 \\-2 & -7\\\end{tabular}$

Explicação passo a passo:

a)

$f(x) = 2x-3\\f(1) = 2(1) - 3 = -1$

b)

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

c)

$f(3) = 2(3) - 3 = 3\\g(1) = -2(1) + 1 = -1\\3 + (-1) = 2$

d)

$g(-2) = -2(-2) + 1 = 5\\f(0) = 2(0)-3 = -3\\5 - (-3) = 8$

e)

$\begin{tabular}{c | l}x & f(x) \\\cline{1-2}0 & -3 \\1 & -1 \\-1 & -5 \\2 & 1 \\-2 & -7\\\end{tabular}$
