STEP - BY - STEP EXPLANATION
What to find?
All values of x that are not in the domain of h.
Given:
Step 1
Determine the domain.
The function h(x) is undefine only at x = 4
Hence, the domain of the function is;
(−∞ , 4) U ( 4, ∞)
Step 2
Find all values of X that are not in the domain.
Clearly, the only value of X that is not in the domain is 4
