What is the domain of the function f(x)=x-3/2x-5

Question

What is the domain of the function f(x)=x-3/2x-5..................

Answer 1

In math, division by zero is undefined.  So any value of x that makes the denominator equal zero would be excluded from the domain.  To find the excluded values, set 2x-5 = 0 and solve for x.  The domain would all x from -∞ to ∞ except for the excluded value(s).
