Explanation:
The function is given below as
The set of domains is given below as
Step 1:
Put x=-1
Step 2:
Put x=0
Step 3:
Put x=1
Step 4:
Put x=2
Hence,
The range of g(x) using set notation will be
Hence,
The graph of g(x) is given below as
Check the picture below.
so, the hyperbola looks like so, clearly a = 6 from the traverse axis, and the "c" distance from the center to a focus has to be from -3±c, as aforementioned above, the tell-tale is that part, therefore, we can see that c = 2√(10).
because the hyperbola opens vertically, the fraction with the positive sign will be the one with the "y" in it, like you see it in the picture, so without further adieu,
