I know how to find the range. My teachers notes phrase it in the form of (for example) (1,sign for infinity). But my multiple choice answers are phrased in a different way. Using the above example, would the range be f(x)greater than or equal to 5 OR x greater than or equal to 5. Sorry for spelling out greater than or equal to and infinity. If mathmatical signs are available on the site I can't see them. I have to turn this in tomorrow so I would appreciate help.
