Answer:
(-∞,19)
Definition: The domain of a function is the set of input or argument values for which the function is real and defined
We know that sum of two sides in any triangle must be greater than the measure of third (longest) side otherwise triangle will not be formed.
According to picture longest side is 18
So this triangle must follow inequality
9+x>18
or 9-9+x>18-9
or x>9
that means value of x must be more than 9.
choices a, c, d are greater than 9 except choice b
Hence choice B-9 is the final answer.
The answer is c. You can plug in the values for x and y and see which ones equal up to 5!
