This part of the question concerns the graph of the function
f (x) = 1/3 (x − 2)^2 − 3.

(i) Explain how the parabola that is the graph of f can be obtained from the graph of y = x^2 by using appropriate translations and scalings.

(ii) Using your answer to part (i), or otherwise, write down the
coordinates of the vertex of the parabola.

(iii) Find the x-intercepts and the y-intercept of the parabola.

(iv) What is the image set of the function f ? (You should express your answer in interval notation.)

Find all asymptotes and holes.

y=(x-1)(x+5) <== that is over (x-6)(x-2)
(x-6)(x-2)

I don't whether it's a normal asymtote, slant, or hole. I also don't know how to start it to figure out the Vertical and Horizontal.
