Multiple Choice: Please select the best answer and click \"submit\". What is the horizontal displacement of the basic graph to produce a graph of y = pie 3 cos(x = Z)

Solution

The basic graph here can be considered as y = cos x

and the horizontal displacement can be measured by observing the change in basic variable

By comparing y = pi + 3 cos (x-2) with y =cos x

We observe that x has been replaced by x-2 , so that would mean that the horizontal displacement

is 2 unit to the right.

Hence option (d) is correct.
