What to do: Write a function that will match the first mountain range in the picture. In the Input bar type: f(x) = sin(x). Then double click on the function on the left side in the Algebra section to manipulate the amplitude A, period k, and phaseshift c. Remember to move the whole function up or down add a number b to the whole function. f(x) = A sin(kx + c) +b. When you are done: Write down the function you created that matches the mountains, you will put it in your journal tomorrow. Go to File, save as, and save it to your computer, Then in another tab, go to, Type the password: mathrocks Then upload the file and logout.
