g(x) = 2 sec (3x - π) + 1

find:

(1) period

(2) domain

(3) range

(4) draw graph

Is the equation for the period is 2π/B (like it is for sine and cosine equations)?

Since the period is the same.

(Answer to your question is yes)

The domain is everywhere except where because division by 0 is not defined.

Range : What is the highest value of ? What is then the minimum value of ? - Jan 15th 2009, 02:19 PMh4hv4hd4si4n
ok, then how do you figure out what the domain is?

Well as I told you is not possible.

I occurs when , In other words

It follows that and when (we don't care because 1 and 3 gives the same set) the function is not defined. - Jan 15th 2009, 03:16 PMh4hv4hd4si4n
