MAT 150 – Class #20 • Topics: • Identify Graphs of Higher-Degree Polynomials Functions • Graph Cubic and Quartic Functions • Find Local Extrema and Absolute Extrema • Modeling Cubic and Quartic Functions
Higher-Degree Polynomial Functions • Higher-degree polynomials functions with degree higher than 2. • Examples:
Two Important Higher-Degree Polynomials • Cubic Function • Quartic Function
Key Features of Higher-Degree Polynomials • In general, the graph of a polynomial function of degree n has at most n x-intercepts. • Local extremaPoints - Turning Points on these graphs • Local minimum point- where the curve changes from decreasing to increasing • Local Maximum point – Where the curve changes from increasing to decreasing • Absolute Maximum Point – the highest point on the graph over an interval • absolute minimum point – The lowest Point on the graph over an interval
Graph • Using the appropriate window, graph . • Find the local maximum and local minimum, if possible. • Where is the absolute maximum of this function on the interval [0, 6]?
Match the Function to the Graph 1 2 5 3 4
Graph Questions Use the given graph to graph to • Estimate the x-intercepts • Turning Points • Positive or negative Coefficient • Cubic or Quartic
