For the function defined by.

f(x) =

{ x^2 , x 1 }

{2x +1, x > 1}

Part II: Graph f(x). A. Graph the rst function completely. (1 point) B. On the same graph you used to answer part (A), graph the second function completely. (1 point) C. Identify the value of xat which the functions change. Remove the parts of each line that are not included in domain of the corresponding function. (2 points) D. Place open and closed circles appropriately on the ends of each line to complete the function. (2 points)
