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.)Ok I thot I posted this before but after a major hunt no find

Was ??? With these options since if f(x) Is a curve going below the x axis Is possible and () vs []

If this is a duplicate post

What is the link.. I normally bookmark these

Mahalo ahead
