I need my work checked please and I’m having trouble with graphing the function.
View attachment 20363
The given function is y = ((x + 4)-2))......................... incorrect
Domain of the given function is: (x + 4) >_ 0
(Since the square root of numbers less than 0 is not possible)
Domain: x _> (-4)
Range: x_> -2
Domain: [-4, ∞)
Range: [-2, ∞)
If the above answers are meant to answer #17 then they are correct.I need my work checked please and I’m having trouble with graphing the function.

What transformations?The function is y = sqrt(x + 4)-2. But your domain and range are correct.
To graph it, what transformations do you apply to the graph of y = sqrt(x)?
What transformations?
Yes. I do know about shifting and translating.Do you know about "shifting" or "translating" a graph?
If not, what methods have you learned for graphing a function like this?
Can you plot:I need my work checked please and I’m having trouble with graphing the function.

No I’m having trouble with plottingCan you plot:
x = (y+2)2 + 4
Now think how is that plot related to the plot of
y = √(x-4) + 2
Can you help me with the drawing? I was having trouble trying to digitally draw the line properly.The important thing is that you got the starting point correctly (indicating the right translations), which is the main point of the exercise; but the shape looks too much like a line, so I might take a little off. The square root function actually starts of vertically before immediately turning downward.
To improve it, I would start by plotting a few familiar points of the original square root function ([MATH]\sqrt{1}[/MATH], [MATH]\sqrt{4}, ...[/MATH]) and then shifting those to plot points on the required graph.
What quadrant is (9,3) in?Well, I can't hold your hand while you do it, so I'm not sure how I can help. Can you draw a curve through (0,0), (1,1), (4,2), and (9,3)?
For (9,3) - both the coordinates (x & y) are positive. What should be the quadrant?What quadrant is (9,3) in?
