Math methods y=√x help

Can someone please help me with this question:
its from the topic y= √x

For each of the following rules, sketch the corresponding graph, giving the axis intercepts when they exist, the set of x-values for which the rule is defined and the set of y-values which the rule takes:
y= −2√3−x  Note: (the square root is for both 3 and -x)

Thanks in advance

I have no idea how to upload an image of the graph but hopefully this helps!

y = -2 x sqrt(-(x-3))
transformations from y = sqrt(x):
dilation of factor 2 from y
reflection in both x and y
translation of 3 units in the positive direction of the x-axis
endpoint: (3, 0)
domain: x <= 3
range: y <= 0
quadrant/s: 3 only

edit: corrected domain and range

just as a reference this is what the graph actually looks like:


domain: x >= 3
range: y >= 0
The domain would actually be (-∞, 3] and range is (-∞, 0]

Oh sorry I haven't logged on in ages so I didn't see this

Nah I did them in year 8 ~ 9, but they didn't work out great and really messed up my foundations in core subjects (english, maths, science) so then I repeated two years to catch up on everything lol. I don't recommend doing vce subjects super early (like, before year 9) if anybody reading is considering.
