I can't discern what the function is. jARe you trying to write ???
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).
