Hi I was hoping someone could help me with a math problem I am confused about. If you could, please use simple steps. Thank you :)

Here is what the problem looks like:

The graph of a parabola passes through the three points (0,3), (1,2), (2,3). Find the values of a, b, c and write the equation of the parabola in the form y = ax^2 + bx +c.
