Solution
For this case the general equation of a parabola is given by:
![y-k=a(x-h)^2](https://img.qammunity.org/2023/formulas/mathematics/college/hscvmrsnstzjmbnhbcg6zpq9vaocly4265.png)
And for this case the vertex is given by:
V= (h= 5, k= 2)
Then replacing we got:
![y-2=a(x-5)^2](https://img.qammunity.org/2023/formulas/mathematics/college/wngs6542xewpraxsf6xfnt4yyna8463qxi.png)
We can use the point given x=6 and y=3 and replacing we got:
![3-2=a(6-5)^2](https://img.qammunity.org/2023/formulas/mathematics/college/c4wuqj49tmtdst9176782ucy3irt7jswes.png)
And we got a= 1
Then the equation would be:
![y=(x-5)^2+2](https://img.qammunity.org/2023/formulas/mathematics/college/6tnf7t0te2cq9qr4owua7chopksp9wyw8h.png)
