The domain of the graphed function is [-2, 1) U (5, 9]
STEP - BY - STEP EXPLANATION
What to find?
The domain of the graph function.
What are domains?
Domains are sets of x- values for which the function is defined.
Observe from the graph given, the function are defined for set of all x - values between -2 and 1 with -2 included.
Also the function is also defined for a set of all x-values between 5 and 9 with 9 included.
This can be represented using interval notation as [-2, 1) U (5, 9].
Therefore, the correct option is A.[-2, 1) U (5, 9].
