What is the value of the rational expression (2x-1)/(x+5) when x = 0? 0 undefined

Question

What is the value of the rational expression
`(2x-1)/(x+5)` when x = 0? 0 undefined

Answer 1

The answer to your question is -1/5

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.
