Answer

Focus = (2, 7)

Explanation

Given:

The following is the equation of a parabola

[tex](y-7)^2=-4x(x-3)[/tex]

What to find:

To find the focus of the parabola.

Step-by-step solution:

The general equation of a parabola can be given as,

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

Comparing the general equation of a parabola with the given equation of a parabola, we have

4p = -4

∴ p = -4/4 = -1

Also,

h = 3

k = 7

Since h ± c = F

We have,

3 - 1 = 2

Therefore, the focus will be (h ± c, k) = (2, 7)
