Here is the graph of the linear function $f(x) = 2x$. It represents a straight line passing through the origin, with a slope of 2.

Would you like any further details or have any questions?

Here are 5 related questions:

1. How would the graph change if the function was $f(x) = 3x$?
2. What is the slope of the line, and what does it represent in this context?
3. How would the graph of $f(x) = 2x + 1$ differ from this one?
4. How do you find the intersection points of the graph with the x-axis and y-axis?
5. What is the general form of a linear function?

Tip: The slope in a linear function controls how steep the line is. A larger slope results in a steeper incline.
