The problem asks to find $g(2)$ given the function $g(x) = 2x - 1$.

To solve this, we simply substitute $x = 2$ into the function:

$g(2) = 2(2) - 1$

$g(2) = 4 - 1 = 3$

So, $g(2) = 3$.

Would you like any further details or explanations? Here are some related questions to consider:

1. What is $g(x)$ if $x = -1$?
2. How do you find the value of $g(x)$ for any given $x$?
3. What is the slope of the function $g(x) = 2x - 1$?
4. How would the graph of the function $g(x) = 2x - 1$ look like?
5. What happens to $g(x)$ as $x$ increases?

Tip: When working with linear functions, always identify the slope (the coefficient of $x$) and the y-intercept (the constant term). This helps in understanding how the function behaves as $x$ changes.
