I just need the answer checked. I would like to especially know if I selected the right graph. I think it's B.

God I hate MyLab Math, not you or your question, just a personal, unasked-for opinion XD

I would agree with you for the proper graph on photo A.( y = cot(x/8) +2 )

When I took pre-calculus, I would always be confused by sin((1/8)*x)+2, try to interpret the fraction in the function as 1/8 times x, which would become x/8.

#

Your Implied Domain is correct too, I believe.

#

and your range is correct as well.

#

Good job!

I hate it too once I got the answer wrong because I didn't list the coordinates of an equation in the order it wanted despite being correct so I emailed my teacher to fix my grade on the quiz and he did 😒

Thank you!
