Question: How do I solve a equation in Maple?

 y = ax^3 + bx^2 + cx + d this is curve and is passing through the points (−1,−4),(1,0),(2,0),(3,−4).
1) Find the values of 𝑎,𝑏,𝑐 and 𝑑.
2) Plot the curve and the points given on the same axis.

I tried solving with derivative of the curve but i didnt find the exact values.
