Question 336566: f(x)= sqrt[4]{15−4x}
Use interval notation to indicate the domain of f(x).
Note: When entering interval notation, use I for infinity, -I for −infinity , and U for the union symbol. If the set is empty, enter "{}" without the quotation marks.
Domain =

The square root function requires non-negative arguments.
4%2815-4x%29%3E=0
15-4x%3E=0
-4x%3E=15
x%3C=15%2F4
So then the domain is,
(-infinity,15%2F4]
