$f(0) = -5$

To solve this problem substitute $color(red)(0)$ for each occurrence of $color(red)(x)$ in the function and the calculate the result.

$f(color(red)(x)) = 2color(red)(x) - 5$ becomes:

$f(color(red)(0)) = (2 xx color(red)(0)) - 5$

$f(color(red)(0)) = 0 - 5$

$f(color(red)(0)) = -5$

If f(x)=2x-5f(x)=2x-5, then what is f(0)?
