Answer:

Explanation:

The equation of a rational function that has a center at (-2, 3) will be of the form:

=

(

)

2

+

(

y=

(x−h)

2

+(y−k)

2

A

+B

Where (h, k) represents the center of the rational function. In this case, (-2, 3) is the center you want.

Looking at the options:

=

2

(

+

2

3

4

y=

(x+2)

2

+3

+4 is a possible option since it has the form we're looking for with the center at (-2, 3).

=

3

2

y=−3/(x+3)−2 does not have a center at (-2, 3).

So, the rational function with a center at (-2, 3) is the first option:

=

2
