Q. 11. a) Use transformations and the cosine function to write three equivalent expressions for the following graph.\newlineb) Use transformations and a different trigonometric function to write three equivalent expressions for the graph.
  1. Divide for yy: Solve for yy by dividing both sides by −3-3.\newliney=x−3y = \frac{x}{-3}
  2. Simplify expression: Simplify the expression. y=−x3y = -\frac{x}{3}
