Question

Construí o gráfico da função afim f(x)-3x+2


Me ajudem por favor ❤

Answer 1

$\large\boxed{\begin{array}{l}\rm f(x)=-3x+2\\\underline{\sf intersecc_{\!\!,}\tilde ao\,do\,gr\acute afico\,com\,eixo\,x:}\\\rm -3x+2=0\\\rm 3x=2\\\rm x=\dfrac{2}{3}\longrightarrow A\bigg(\dfrac{2}{3},0\bigg)\\\underline{\sf intersecc_{\!\!,}\tilde ao\,do\,gr\acute afico\,com\,eixo\,y:}\\\rm f(0)=-3\cdot0+2\\\rm f(0)=2\longrightarrow B(0,2)\\\rm O\,gr\acute afico\,est\acute a\,anexo.\end{array}}$
