Question

Determine o gráfico, o domínio e a imagem da função f(x) = -2 + senx.​

Answer 1

$\large\boxed{\begin{array}{c|l|c|l}\sf x&\sf sen(x)&\sf-2+sen(x)\\\sf0&\sf0&\sf-2+0=-2\\\sf\dfrac{\pi}{2}&\sf1&\sf-2+1=-1\\\sf\pi&\sf0&\sf-2+0=-2\\\sf\dfrac{3\pi}{2}&\sf-1&\sf-2-1=-3\\\sf2\pi&\sf0&\sf-2+0=-2\end{array}}$

$\Large\boxed{\begin{array}{l}\sf f(x)=-2+sen(x)\\\sf D=x\in[0,2\pi]\\\sf Im=[-3,-1]\\\sf o~gr\acute afico~est\acute a~anexo\end{array}}$
