Answer:


\boxed{A.\:\:y=(2x+7)/(x-3)}

Explanation:

If the rational function has a vertical asymptote at
x=3.

Then the denominator of the rational function is
(x-3)

If the function has a horizontal asymptote of
y=2, then the leading coefficient of the numerator and the leading coefficient of the denominator must be in the ratio
2:1

The only function that has the above properties is


y=(2x+7)/(x-3)

The correct answer is A.

Answer:

The rational function satisfying the given conditions is contained in choice A

Explanation:

The vertical asymptote is evaluated by determining the value of x that makes the function in the denominator equal to zero and in this case it is;x=3.

On the other hand, the leading coefficient of the function in the numerator avails information regarding the horizontal asymptote; in this case y=2
