Determine the domain of the function
2 answers:
Answer:
Option B is correct.
The domain of the function h(x) is: 
Step-by-step explanation:
Domain states that the complete set of all the possible values of the independent variable where function is defined.
Given the function:

To find the excluded value in the domain of the function.
equate the denominator to 0 and solve for x.
i.e

⇒x = 0 and 
⇒x = 0 and 
or
x = 0 and 
So, the domain of the function h(x) is the set of all real number except x = 0 and 
Therefore, the domain of the function h(x) is:

Answer:
Choice b is correct.
Step-by-step explanation:
We have to find the domain of the given function.
The given function is 9x/x(x²-36).
Domain is the all possible values of x for which the function is defined.
so the function is undefined when x(x²-36) = 0.
So,
x(x²-36) =0
either x = 0 or (x² -36) =0
x=0 or x²= 36
x=0 or x = ±6
So, the domain of function is the set of real numbers except x=0 and x = ±6.
