Which is the correct input-output table for the function ?f(x)=3/x+4
Amanda [17]
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.
