Após analisar o gráfico, assinale a alternativa correta:

$\displaystyle{D}{\left({R}\right)}={\left\lbrace{x}\in\mathbb{R}\//{1}<{x}<{2}\right\rbrace}$
$\displaystyle{R}={\left\lbrace{\left({x},{y}\right)}\in{A}\times{B}\//{y}={2}{x}\right\rbrace}$
$\displaystyle{I}{m}{\left({R}\right)}={\left\lbrace{x}\in{R}\//{2}<{x}<{4}\right\rbrace}$

$\displaystyle{I}{m}{\left({R}\right)}={\left\lbrace{y}\in\mathbb{R}\//{1}<{y}<{3}\right\rbrace}$

$\displaystyle{A}={\left\lbrace{x}\in{R}\//{1}\le{x}\le{4}\right\rbrace}$
