Question

Considere a função f(x) = 3x + 1, determine a taxa média de variação de f(2) e f(4).

Answer 1

✅ Função do primeiro grau:

Sendo a função do primeiro grau:

             $\large\displaystyle\begin{gathered} \mathfrank{f(x) = 3x + 1} \end{gathered}$

Para calcular a taxa média de variação "Tm" entre f(2) e f(4), fazemos:

           $\large\displaystyle\text{ \begin{gathered} \mathfrank{T_{M} = \frac{f(2) + f(4)}{2} } \end{gathered} }$

                  $\large\displaystyle\text{ \begin{gathered} \mathfrank{= \frac{3.2 + 1 + 3.4 + 1}{2} } \end{gathered} }$

                  $\large\displaystyle\text{ \begin{gathered} \mathfrank{= \frac{6 + 1 + 12 + 1}{2} } \end{gathered} }$

                  $\large\displaystyle\text{ \begin{gathered} \mathfrank{= \frac{20}{2} } \end{gathered} }$

                  $\large\displaystyle\begin{gathered} \mathfrank{= 10} \end{gathered}$

✅ Portanto, a resposta é:

           $\large\displaystyle\text{ \begin{gathered} \mathfrank{T_{M} = 10 } \end{gathered} }$
