Find the domain of the function. Write your answer in interval notation.

Question

f (x)=5/(x2-x)

Answer 1

Factor the denominator and see where it is zero, and that will tell you the restrictions.

 

f(x) = 5 / [x(x - 1)]

 

The domain is all real numbers except 0 and 1.  You can express it in interval notation.
