Answer

Step 3: The domain of the difference of the functions f(x)g(x) is the set of all x-values that are in both the domain of f and the domain of g. This means that we need to find the intersection of the two domains. The intersection of x0 and x0 is x>0.

Steps

Step 1 :Step 1: We need to find the domain of each individual function first. The domain of f(x)=x is x0, because we cannot take the square root of a negative number.

Step 2 :Step 2: The domain of g(x)=1x is x0, because we cannot divide by zero.

Step 3 :Step 3: The domain of the difference of the functions f(x)g(x) is the set of all x-values that are in both the domain of f and the domain of g. This means that we need to find the intersection of the two domains. The intersection of x0 and x0 is x>0.
