Graph the function y=-2cos2蟺-x.

Short Answer

Expert verified

The graph is

Step by step solution

01

Step 1. Given Information

The given function isy=-2cos2蟺-x.

02

Step 2. Plot the graph of cos function 

  • Plot the graph of y=cosx.

03

Step 2. Scale the Graph

  • Reverse the obtained graph upside down to obtain the graph of y=-cosx.
  • Then scale the graph by the scaling factor of 2.

  • The dotted line represents y=cos(x)and the solid line represents y=-2cosx.
  • The period of cosxis 2蟺, so, the period of -2cos2蟺-xwill also be 2蟺.
  • So, the solid line is the required graph.
