Question 1156296: Draw the letter “W” on your axes, wherever you want on the coordinate system. You can include the origin in your graph or not, as you choose. Make sure that the endpoints of all legs of the W are at distinct points on the graph, and label the coordinates of those points. Make sure that there are at least
4 units of distance between each of the “corners” of the letter (distances don’t have to be whole units,just > 4 units). Write the piecewise-function definition of your graph. Include the sections of the Domain, and list the function definitions in order of the
sections of the Domain. Include one example of calculations you used in finding the function definitions.
