Identifying a graph?

  1. Sep 20, 2004 #1
    Does anyone know how to go about this? I had to draw this, so I'm not sure how good it is, but any help would be appreciated.

    What information did you use to draw the graph?

    I will assume that the 2 branches should be symmetric. If so, it looks like it could be -csc(x). But you really have not given enough information to be sure of answer.

    I didn't use any information to draw the graph. It was a picture and they asked what to identify it. So the answer should be f(x) = ?

    It could be -csc(2x).

    I'm sure that's not the answer. Actually, the choices are a) f(x) = 3sec(2x + n), b) f(x) = 3csc(2x -2pie), c) f(x) = 3csc(2x + pie), or d) f(x) = 3sec(2x - pie).

    Maybe that'll help.

    consider the minimal f(x) which is 3 in all cases .... find x and then look at the graph.
