I need help with these, there are already filled in just if anyone knows these off the top of their head it would be greatly appreciated. Thank you

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.
