Answer:
Amplitude = 3
Step-by-step explanation:
The amplitude of a sinusoidal function is HALF of the difference between MAX and MIN points of the graph.
The graph shown isn't centered at x-axis. Now, we look where the maximum point is. Each unit of graph is "1" units.
The max point is at y = 1
Now, we look for minimum point. Thus,
the min point is at y = -5
The vertical distance is:
1 - (-5) = 1 + 5 = 6 units
The amplitude is HALF of this vertical distance, so
Amplitude = 6/2 = 3
Amplitude = 3
on the matrix gives![\left[\begin{array}{cc|c}5&5&5\\1&-\dfrac23&5\end{array}\right]\to\left[\begin{array}{cc|c}1&-\dfrac23&5\\5&5&5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D5%265%265%5C%5C1%26-%5Cdfrac23%265%5Cend%7Barray%7D%5Cright%5D%5Cto%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%26-%5Cdfrac23%265%5C%5C5%265%265%5Cend%7Barray%7D%5Cright%5D)
