3- Para as funções abaixo: Calcule a raiz ou zero da função e construa o gráfico para cada função. \( \begin{array}{llll}61 x 1-2 & f(x)=2 . x+98 & f(x)=-73 . x+60 & f(x)=-5 . x+35\end{array} \)

Quick Answer
Para calcular as raízes das funções, igualamos cada função a zero e resolvemos para \(x\). As raízes são:
- \(f_1(x) = 61x - 2\) tem raiz em \(x \approx 0,0328\)
- \(f_2(x) = 2x + 98\) tem raiz em \(x = -49\)
- \(f_3(x) = -73x + 60\) tem raiz em \(x \approx 0,8219\)
- \(f_4(x) = -5x + 35\) tem raiz em \(x = 7\)
Os gráficos podem ser desenhados com base nas características das funções.
