Question

genteeee, como faz o gráfico dessa função modular???

Y=|x+2|+x-1​

Answer 1

$\large\boxed{\begin{array}{l}\rm y=|x+2|+x-1\\\rm se\,x\geqslant-2:\\\rm y=x+2+x-1\\\rm y=2x+1\\\underline{\sf\,veja\,anexo\,1}\end{array}}$

$\large\boxed{\begin{array}{l}\rm se\,x<-2:\\\rm y=-(x+2)+x-1\\\rm y=-\backslash\!\!\!x-2+\backslash\!\!\!x-1\\\rm y=-3\\\underline{\sf veja\,anexo\,2}\end{array}}$

$\large\boxed{\begin{array}{l}\rm o\,gr\acute afico\,da\,pergunta\\\rm \acute e\,obtido\,unindo\,os\,gr\acute aficos\,das\\\rm sentenc_{\!\!,}as\,anteriores.\\\underline{\sf Veja\,anexo\,3}\end{array}}$
