Graphs of Polynomial Functions
... Another example: Find all the real zeros and turning points of the graph of f (x) = x 4 – x3 – 2x2. Factor completely: f (x) = x 4 – x3 – 2x2 = x2(x + 1)(x – 2). The real zeros are x = –1, x = 0, and x = 2. These correspond to the x-intercepts (–1, 0), (0, 0) and (2, 0). The graph shows that there ...
