k is the "multiplier". There are an infinite number of cubic equations that have the roots x = 1, x = 1 and x = 3 as in part (i). The specific function is the factors multiplied by the specific multiplier. The value of k is found by the constraint that is contains another specific point other than the roots in part (i) we know that it contains (0, 3) i.e. if we input 0 it will give us an output of 0. This means that k=1 so now we know that this curve is 1 multiplied by the factors.
