Graph of y=−3cos⁡(2x−π)

The graph of y=−3cos⁡(2x−π) is a type of trigonometric function, specifically a cosine function with a negative coefficient and a phase shift. In this article, we will explore the properties and characteristics of this graph, including its amplitude, period, and phase shift.

The graph of y=−3cos⁡(2x−π) can be broken down into three main components:

Amplitude: The amplitude of a cosine function is the maximum value that the function reaches. In this case, the amplitude is 3, which means that the graph will reach a maximum value of 3 and a minimum value of -3.
Period: The period of a cosine function is the distance between two consecutive points on the graph that have the same y-value. In this case, the period is π/2, which means that the graph will repeat itself every π/2 units.
Phase Shift: The phase shift of a cosine function is the horizontal shift of the graph. In this case, the phase shift is π/2, which means that the graph will be shifted to the right by π/2 units.

The graph of y=−3cos⁡(2x−π) has several characteristics that are worth noting:

Symmetry: The graph is symmetric about the x-axis, which means that it has an even function.
Periodicity: The graph is periodic, which means that it repeats itself every π/2 units.
