a) f(0)
b) f(1)
c) f(2)​

Answer 1

Resposta:

OLÁ

• ❊ para calcular basta substituir as letras pelos números

A)

$\boxed{ \begin{array}{c} \\ \\ \large{ \sf{f(x) = 3x - 7 }}\\ \large{ \sf{f(0) = 3 \times 0 - 7}} \\ \large{ \sf{f(0) = 0 - 7}} \\ \large{ \sf{ \blue{f(0) = - 7}}} \\ \\ \end{array}}$

B)

$\boxed{ \begin{array}{c} \\ \\ \large{ \sf{f(x) = 3x - 7}} \\ \large{ \sf{f(1) = 3 \times 1 - 7}} \\\large{ \sf{f(1) = 3 - 7}} \\\large{ \sf{ \blue{f(1) = - 4}}} \\ \\ \end{array}}$

C)

$\boxed{ \begin{array}{c} \\ \\ \large{ \sf{f(x) = 3x - 7}} \\ \large{ \sf{ f(2) = 3 \times 2 - 7}} \\ \large{ \sf{f(2) = 6 - 7}} \\ \large{ \sf{ \blue{f(2) = - 1}}} \\ \\ \end{array}}$
