Find the domain of the function.

Question

Find the domain of the function. (Enter your answer using interval notation.)

f(x)= 1/x-4

Answer 1

if you mean f(x) = 1/(x-4), the domain is

(-infinity,4)U(4,infinity)

but if you meant f(x) = (1/x)-4 the domain is

(-infinity,0)U(0, infinity)

the domain is all real numbers that don't make the denominator = 0
