The cordinates of the graph are (π, -0.7071) (2π, 0.7071) (3π,-0.7071) similarly for (-π, -0.7071) (-2π, 0.7071)

Explanation:

The function f(x)= cos(x-45)

Can be written as y=cos(x-45)

To find the coordinates of the provided function we proceed by taking the value of x as given below in the table

f(x)= cos(x-45)

Value of “x” f(x)

π -0.7071

2π 0.7071

3π -0.7071

4π 0.7071

5π -0.7071

-π -0.7071

-2π 0.7071

-3π -0.7071

-4π 0.7071

-5π -0.7071

Thus, we see that cosine function is exhibiting cyclicity at the interval of

The given x and y coordinates can be plotted on the graph to find the interval
