Answer:
• Amplitude = 2
,
• Period = π/4
Explanation:
Given the function:
[tex]y=-2\sin(8x)[/tex]
In order to sketch the graph of y, we need to find its amplitude and period.
Comparing the function with the general sine function:
[tex]y=a\sin(bx+c)+d[/tex]
We have that:
[tex]\begin{gathered} Amplitude=|a|=|-2|=2 \\ Period=\frac{2\pi}{|b|}=\frac{2\pi}{8}=\frac{1}{4}\pi \end{gathered}[/tex]
Next, using these values, we sketch one cycle of the graph below:
