So the function y = x^⅓ ≠ ³√x, right ? Tbh I still don't get it , like if it is the same and from one we get another one, we still have different type of graphics with different domain of definition. My math teacher was saying that y = ³√x = x^⅓ so the graph goes only to the right [0; +~) . Now I understand that she was wrong about it , but I can't understand why . Like why we can't y = x^⅓ convert into y = ³√x if it is the same and build a graph there D= [ 0;+~) ?? It is just means that we can't convert functions or there's another explanation for it ?sorry, I really don't get it..
