2. Match each equation with the corresponding graph of a polynomial function. Justify your choices (i.e. the type of function and whether it is of even or odd degree; the end behaviour of the graph of the function; the number of possible x-intercepts; whether the graph will have a maximum or minimum value; the y-intercept).
