Question

What would be the maximum value of the function for the graph shown if we consider the graph to be a cosine function of the form y = a cos (x - c)?
0

2

-4

-2

Answer 1

Answer:

2

Step-by-step explanation:

The maximum value is the amplitude. Looking at graph, it would be the highest point in the graph.

Each unit of the graph is 2 units, hence the maximum value, clearly looking at the graph, would be y = 2. Also the minimum value is y = -2.

So, the maximum value is 2
