Your descriptors are mostly correct, assuming the column headings are something like ...
... function ... domain ... range ... odd/even ... intercepts ... increasing/decreasing ... ??? ... critical points
_____
√x is increasing on the interval [0, ∞). There is no branch where the function is decreasing.
1/x has a critical point at x=0. The slope is undefined there.
6 because you would take 3/4 / 1/8 and then continue to follow the reciprocal to get 24/4 which is 6.
I think its a context clue for a producer or well an inorganic chemical reaction.
