Answer:
[tex]y=\frac{5}{x+3}[/tex]
Step-by-step explanation:
A rational function is defined as the quotient of polynomials whenever the denominator has a degree of at least 1. Put another way, the denominator must have a variable in it. So the form of a rational function is:
[tex]y=\frac{p(x)}{q(x)} \\ \\ Whenever \ q(x) \neq 0[/tex]
From the options:
- B and C aren't functions at all because [tex]y[/tex] doesn't exist. They are equations.
- D is a linear function
- A satisfies the conditions of rational functions.
So the correct option is A.
