Answer:

B

Explanation:

To determine the correct table of input/outputs, take each input, substitute it into the function for "x", evaluate, and see if it equals the output. If it works for ALL of the pairs, then it is the correct table. Since functions only have one output for any input, there can't be two correct answers.


f(x)=(3)/(x)+4

Check x = -3


f(-3)=(3)/((-3))+4\\=-1+4\\=3\\f(-3)\overset{\checkmark}{=}3

Check x = -2


f(-2)=(3)/((-2))+4\\=-1.5+4\\=2.5\\f(-2)\overset{\checkmark}{=}2.5

Check x = 1


f(1)=(3)/((1))+4\\=3+4\\=7\\f(1)\overset{\checkmark}{=}7

Check x = 2


f(2)=(3)/((2))+4\\=1.5+4\\=5.5\\f(2)\overset{\checkmark}{=}5.5

Check x = 3


f(3)=(3)/((3))+4\\=1+4\\=5\\f(3)\overset{\checkmark}{=}5
