Answer:
The amplitude is 3 and the period is 10π/9.
Step-by-step explanation:
The standard cosine function is in the form:
Where |<em>a</em>| is the amplitude, 2π/<em>b</em> is the period, <em>c</em> is the phase shift, and <em>d </em>is the vertical shift.
We have the function:
We can rewrite this as:
Therefore, <em>a</em> = 3, <em>b</em> = 9/5, <em>c</em> = 0, and <em>d</em> = 0.
Hence, our amplitude is |3| = 3.
Our period will be:
