5. (10 points) Investigate, using Dynamic Geometry Software to find the connection between x-intercepts and the shape of the graph of the polynomial function (k,t). And then sketch the graph (k).(C1.5) 6. (10 points) Compare finite differences in tables of values (k,t); investigate the maximum number of x-intercepts for the polynomial function by using Graphing Calculator, Fathom, or Spreadsheet (k,t).(C1.2) 7. (4 points)Investigate numerically, graphically, and algebraically, whether this polynomial function is even, odd, or neither. And then determine its properties. (k,t)(C1.9)
