Which graph represents the function f(x) = log10(x + 2)?

You can see a graph of that function.

Here I also show you a table with some points. First take into account tha the domain is x > - 2 and that the limit of the function as x goest to - 2 is negative infinity.

x                         f(x)

- 1.999999999     -9

-1.99                    -2

-1.9                      -1

-1                           0

0                            0.301

1                            0.477

8                            1

98                          2

998                        3

∞                           ∞

With this information and the graph you can identity which of your graphs is the right one.
