Question 1111200: For​ f(x) as​ given, write domain of f.
f(x)=15−3x
The domain of f is
x≤5 < This is what I have so far, but how do I put that in interval notation?

What you got so far is wrong. 

The correct answer is:  


    the domain for the given function  f(x) = 15-3x  is the set of all real numbers.

    In the interval notation this set is  (-infinity,infinity).
