f > -1 and f < 5

Does this mean I just graph those 2 or solve them and find the intersection then graph?

**Reiny**, Tuesday, January 5, 2010 at 10:29pmYou should really give yourself a "nickname".

Are you the same 'anonymous' who asked a similar question before?

In that reply I showed how you can change

f > -1 and f < 5 to

-1 < f < 5

on a number line, draw open circles around the -1 and 5 and join them with a solid line.

That is the generally accepted way.
