Question

write the domain of the following real functions f(x)= 2x+1÷x-9​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The domain of given function is all real number except 9.

Step-by-step explanation:

The given function is

$f(x)=\dfrac{2x+1}{x-9}$

We need to find the domain of the given function.

Numerator is (2x+1) and denominator is (x-9) which are polynomial. Domain of  all real number.

It means the given function is defined for all values of x, except those values for which the value of denominator is equal to 0.

$x-9=0$

$x=9$

The value of denominator is equal to 0 at x=9.

Domain = R - {9}

Therefore, the domain of given function is all real number except 9.
