Some functions that aren't invertible can be made invertible by restricting their domains. For example, the function x^2 is invertible if we restrict x to the interval [0,inf), or to any subset of that interval. In that case, the inverse function is \sqrt

Over which of the following domains is f(x) = csc(0.1x + 1.2) defined at all points and invertible? a. x = [0,10] b. x = [10,20] c. x = [20,30] d. x = [30,40] I know it's either a or d since 20 is an asymptote, I'm just not sure which one.
