0.2 Construa o gráfico f(x) = 2 + sen x


ME AJUDEM É PRA HOJE PFV

Answer 1

Resposta:

Explicação passo-a-passo:

1)

Construa a tabela e com os valores de x e y construa o gráfico (ver em anexo)

$\displaystyle \begin{equation}\begin{array}{lllll}x&|&cos(x) &|& y=3cos(x) \\\\ \nonumber0 &|&1 &|& 3 \\\\\frac{\pi}{2}&|&0 &|& 0 \\\\\pi&|&-1&|&-3 \\\\\frac{3\pi}{2}&|&0 &|&0 \\\\\pi&|&1&|&3 \\\\\end{array}\end{equation}$

2)

Construa a tabela e com os valores de x e y construa o gráfico (ver em anexo)

$\displaystyle \begin{equation}\begin{array}{lllll}x&|&sen(x) &|& y=2+sen(x) \\\\ \nonumber0 &|&0 &|& 2 \\\\\frac{\pi}{2}&|&1 &|& 3 \\\\\pi&|&0&|&2 \\\\\frac{3\pi}{2}&|&-1 &|&1 \\\\\pi&|&0&|&2 \\\\\end{array}\end{equation}$
