3. f(x) = cos(x - 45°)

Please help with finding the coordinates

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

Step-by-step 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

the answer is d. 75%
