Answer:

Step-by-step explanation:
The general form of a parabola is

Now, we have three points, where each of them gives values for (x,y). We can use them to create a system of three equations with three unknown variables

Then, we replace the value of
in the second and third equation to find create an equation with only two variables


Then, we multiply the first equation by 2, and sum both equations


Finally, we use this value to find 

Therefore, the equation of the parabola is
