(a) The graph of f behaves like y = -infinity for large values of |x|(b) The x intercept are : -7, 0, 7 The y intercept is : 0(c) The zeros of f are : -7, 0, 7 The smallest zero is the zero of multiplicity 1, so the graph of f crosses the x axis at x = -7. The middle zero is the zero of multiplicity 1, so the graph of f crosses the x axis at x = 0. The largest zero is the zero of multiplicity 1, so the graph of f crosses the x axis at x = 7. (d) The graph will have atmost 2 turning points. (e) option - a is the answer
