Inverse Functions!??hi..I need help with these two questions from my Review Sheet... #2 20051230 10:29:38
Re: Inverse Functions!??I way: IPBLE: Increasing Performance By Lowering Expectations. #3 20051230 10:34:02
Re: Inverse Functions!??2) x^2 hasn't inverse function because there exist two solutions of IPBLE: Increasing Performance By Lowering Expectations. #4 20051230 10:37:20
Re: Inverse Functions!??But we may say: IPBLE: Increasing Performance By Lowering Expectations. #5 20051230 10:43:25

Re: Inverse Functions!??Two ways you can prove it? The only way I know is this: Last edited by mikau (20051230 11:43:51) A logarithm is just a misspelled algorithm. #7 20051230 11:54:24
Re: Inverse Functions!??Ah, I forgot. The graphs of an inverse function is the graph of the original function, reflected about the line y = x. So you could also draw a graph of the two functions and determine whether they appear to be relfections about the line y = x.
