If f(x)=x-3/x and g(x) = 5x – 4, what is the domain of (fog)(x)?​

x = 4/5 is the one x value that is not permitted.  The domain of (fog)(x) is

(-infinity, 4/5) ∪ (4/5, infinity)

Step-by-step explanation:

(fog)(x) is the "composition" of f and g.  We start with f(x) and replace x with g(x), which is 5x - 4:

              3

f(x) = x - becomes

               x

                                          3            

f(5x - 4) =     [5x - 4]  -  

                                      [5x - 4]

To identify the domain, consider the value or values of x for which the denominator shown above is zero:  5x - 4 = 0, or 5x = 4, or x = 4/5

∠cbe and ∠deb are same-side interior angles.
