Steps for Using a Graphing Utility to Analyze the Graph of a Polynomial Function STEP 1: Determine the end behavior of the graph of the function. STEP 2: Graph the function using a graphing utility. STEP 3: Use the graphing utility to approximate the x- and y-intercepts of the graph. STEP 4: Use the graphing utility to create a TABLE to find points on the graph around each x-intercept. STEP 5: Approximate the turning points of the graph. STEP 6: Use the information in Steps 1 through 5 to draw a complete graph of the function by hand. STEP 7: From the graph, find the range of the polynomial function. STEP 8: Use the graph to determine where the function is increasing and where it is decreasing.
