## anonymous one year ago What is the domain of the function given in INTERVAL NOTATION:

1. anonymous

y=-3sec(pi-2x)+5

2. anonymous

we need to find the period and where the 1/costhteta =0

3. anonymous

its 2

4. anonymous

the period is 2

5. anonymous

i would disagree and say the period is pi shifted pi to the right and reflected

6. anonymous

ok

7. anonymous

but how do we go from there to interval notation

8. anonymous

$\:[0,\:\frac{\pi }{4})\cup \left(\frac{\pi }{4},\:\frac{3\pi }{4}\right)\cup \left(\frac{3\pi }{4},\:\frac{5\pi }{4}\right)\cup \left(\frac{5\pi }{4},\:\frac{7\pi }{4}\right)\cup (\frac{7\pi }{4},\:2\pi ]$

9. anonymous

is that the domain

10. anonymous

@mathstudent55 am I right now?

11. anonymous

@Deeezzzz am I right now?

12. anonymous

yes that is correct
