3. For the function defined by: (2x+1 *>1/ Part I: Evaluate (0) A. Identify the function that will be used when x = 0. (1 point) B. Find the value of this function when x = 0. (1 point) f(0)=0^2=0 Part II: Graph f(x). A. Graph the first 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 x at 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 complete the
