What is the focus of the parabola given by the equation y = x2 − 2x − 3?

What is the focus of the parabola given by the equation y = x2 − 2x − 3?
y = x2 − 2x − 3
y = x2 − 2x − 3 -1 +1y = (x - 1)^2 - 4 h = 1 and  k = - 4 and  a = 1

Vertex (a, k) so it is  (1,-4)

Now focus is
(1, -4 + 1/4) = (1,-3 3/4)
or
(1,-3.75)

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
