Note: The question does not include the form mentioned. However, I will go ahead to highlight the general features of the polynomial function f(x) shown:
From the plotted grapph of the polynomial function f(x) shown, there are a lot of features that can be deduced:
1) As x tends to -ve infinity (i.e. x → -∞), f(x) tends +ve infinity (i.e. f(x) → ∞)
2) As x tends to +ve infinity (i.e. x → ∞), f(x) tends to +ve infinity (i.e. f(x) → ∞)
3) f(x) has a minimum at x tends to 0 (i.e. x → 0)
4) The polynomial function f(x) has 4 zeros. (That is the point where f(x) = 0). It is also the point where the graph crosses the x axis
