Question

Construa o gráfico da função polinomial do 1º grau, sendo f:R-R. : f(x) = 2x​

Answer 1

$\large\boxed{\begin{array}{l}\rm f(x)=2x\\\rm f(-2)=2\cdot(-2)=-4\\\rm f(-1)=2\cdot(-1)=-2\\\rm f(0)=2\cdot0=0\\\rm f(1)=2\cdot1=2\\\rm f(2)=2\cdot2=4\\\boxed{\begin{array}{c|c}\rm x&\rm f(x)\\\rm -2&-4\\\rm-1&\rm-2\\\rm 0&\rm0\\\rm 1&\rm2\\\rm 2&\rm4\end{array}}\\\underline{\sf o\,gr\acute afico\,est\acute a\,anexo}\end{array}}$
