Thank you for the opportunity to help you with your question!

local maximum=(3,1)

local minimum=(3,-7)

y=3+3x-6

y=3x-3

Please let me know if you need any clarification. I'm always happy to answer your questions.

Thank you, but the local maximum is not (3, 1). It is (-PI / 3, 1). I cannot type the Greek symbol PI but it is PI, which equals 180 degrees. The local minimum is also not (3, -7). It is (2PI / 3, -7).
