Clarification on this function
I'm trying to draw the graph of the function =(x-4)^{\frac{2}{3}})
and I'm a little confused. Firstly, is the y-intercept:
^{\frac{2}{3}})
?
Because when I entered this function into an online graphing calculator, it showed the graph only existing on 
. I also tried inputting it on WolframAlpha and got to a completely different graph: http://www.wolframalpha.com/input/?i=(x-4)^(2/3)
