Which of the following valued of x is not in the domain of f(x) = x+3 / x-7
1 answer:
Answer:
x = 7 is not there in the domain of the function.
Step-by-step explanation:
The given function is f(x) =
We have to find out which all values are not there in the domain of the function.For the function to become not defined the function should have infinite value and this happens when the denominator becomes zero.
In the given function for the denominator to become zero , the value of x must be 7.
For all other values of x , the function is defined.
Hence , the domain of x is all real numbers except 7.
