At which points are is the function continuous?
y = (3x - 1)^(1/4)
The function is continuous at the interval [1/3, infinity). Discontinuous at (-infinity,1/3] because a negative answer is obtained.
So to apply the continuity tests, do I just substitute in any internal point and prove what I said above is correct?
Also did I use the brackets and parenthesis correctly in writing an interval or does it not matter?
