Answer:

The equation of the parabola is [tex](x-3)^2 = 16(y-1)[/tex].

Step-by-step explanation:

It is given that the vertex of a parabola is at the point (3,1), and its focus is at (3,5).

Let the equation of parabola is

[tex](x-h)^2 = 4p(y-k)[/tex]

Where, (h,k) is vertex and (h,k+p) is focus.

The vertex of a parabola is at the point (3,1). So, the equation of parabola is

[tex](x-3)^2 = 4p(y-1)[/tex]

Focus of the parabola is (3,5),

[tex](h,k+p)=(3,5)[/tex]

[tex](3,1+p)=(3,5)[/tex]

Compare both sides.

[tex]1+p=5[/tex]

[tex]p=4[/tex]

Therefore the equation of the parabola is

[tex](x-3)^2 = 4(4)(y-1)[/tex]

[tex](x-3)^2 = 16(y-1)[/tex]
