Take the general equation of a parabola with coefficients  "a",  "b"  and  "c".

Using the given info, construct three linear equations for these three unknowns "a",  "b"  and  "c".

Then solve the system by any way you can.

You can use the solver of your calculator or any  (free of charge)  of numerous solvers from the Internet.
