Y = the absolute value of x ^ 2-2x-3. Find the definition field and value field. How to spend drawing

Domain x ∈ R
Range Y > = 0
You first draw the graph of y = x ^ 2-2x-3, and then fold it up along the X axis to get the graph of the absolute value of y = x ^ 2-2x-3
You can draw the image of F (x) first and then fold it up along the X axis to get the image of y = f (x)
