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.
