    Is the first vertex of this equation a min or max?

    Hi,

    I'm a little confused because the answer key differs with the answer I found, so could someone tell me if the first vertex of the equation 2sin-(pi-x)+1 is a max or a minimum? I factored out the negative to get it into the right format (x-h) so that b and a are both positive, but the answer key has b negative (form is asinb(x-h)+k).

    Thanks!

    I can't discern what the function is. jARe you trying to write 2sin[-(\pi -x)}]+1 ???

    Well, that is, of course, the same as 2 sin(x- \pi)+ 1. What does sin(x) look like just above x= -\pi?

    I am crazy! I hate min and max!
