Since we aren't given any real information about f(x) we need to be general. It's possible that f(x) can be just about anywhere is this interval. But note that the (continuous) function has to go from f(2) = 10 to f(4) = 20. So it has somehow get to 20 from 10. At some point the function has to hit every value between 10 and 20. (See the image for a visual.)

Would not your free hand line not be a function failing a vertical line test

I'm just saying that f(x) can be anything so I had fun sketching it.
