64 1/2 solve in indices

The answer to your question is   -1/5

Step-by-step explanation:

Data

          f(x) = (2x - 1) / (x + 5)

when x = 0

Process

1.- Substitute the value of x in the function

          f(0) = (2(0) - 1) / (0 + 5)

2.- Simplification

          f(0) = (0 - 1) / 5

3.- Result

          f(0) = -1/5

This expression was not difficult to solve because 0 is not undefined.
