Hi. I need to find the intercepts, domain and range, is it a function?, even or odd?, and is it a one-to-one function?
y=cot (x)
-domain: (negative infinity, 0) U (0,infinity)
-range: all real numbers
-x-intercept: none
-y-intercept: none
-is not a function
-It is neither
-It is not one-to-one
Please help me. I am totally confused what to do and I am not sure if my answers are right. Any help would be greatly appreciated.
