For the answer to the question above,
It seems the function f(x) is 3/(x+4).

If the function is f(x) = 3 / (x + 4), a table could be

x f(x)

-8 -3/4

-7 -1

-6    -3/2

-5    -1

(-4 is no a valid input)

- 3 3

- 2    3/2

-1    1

0 3/4

1    3/5

2    3/6 = 1/2

3    3/7

4    3/8

If the function is f(x) = (3/x) + 4

Just substitute different values for x and obtain the respective outputs. In this case, x has to be different of o, i.e. 0 is not a valid input.

Its the second choice.

These are the options (0,-5) (4,-2) (8,2) (-16,-17) (-1,-8) (-40,-34)

All you need to do is plug in the points!

Here we go:

3(0)- 4(-5)-8

If it equals 12, then it is a point and an answer.

3(0)- 4(-5)-8= 12

(0,-5) is a point!

Next one:

3(4)-4(-2)-8

12+8-8
That equals twelve. (4,-2) is an answer as well!

I am going to quickly plug in the rest of the points, since I think you have the idea.
(8,2) 3(8)-4(2)-8= 8 This is not an answer.
(-16,-17) 3(-16)-4(-17)-8 = 12 This is answer.
(-1,-8) 3 (-1)-4(-8)-8= 21 This is not an answer.
(-40,-34) 3(-40)-4(-34)-8= 8 This is not an answer.

I hope this helped you!

Brainliest answer is always appreciated!
