To find the domain of the function
, we need to determine the possible values of
for which the function is defined.The function
is defined for all real values of
. This is because the square of any real number is always non-negative, and multiplying it by -9 will result in a negative value. Therefore, there are no restrictions on the values of
.Hence, the domain of the function
is all real numbers, which can be represented as
.Therefore, the correct answer is C.
.
