QuestionDetermine whether f is a rational function and state its domain. $$f(x)=\frac{x^{3}-3 x+5}{2 x-7}$$
Is f a rational function? Yes No What is the domain of $f$ ? Select the correct choice below and, if neces box to complete your choice. A. $D=\{x \mid x \geq$ $\square$ \} (Type an integer or a simplified fraction.) B. $D=\{x \mid x \neq$ $\square$ 3 (Type an integer or a simplified fraction. Use a comma to sepe as needed.) C. $D=\{x \mid x<$ $\square$ 3 (Type an integer or a simplified fraction.) D. The domain is all real numbers.
