Question

If the instructions for a problem ask you to use the smallest possible domain to completely graph two periods of y = 5 + 3 cos 2(x - pi/3), what should be used for Xmin and Xmax?

Answer 1

you have an infinite number of choices

Answer 2

What would you start with/recommend? @satellite73

Answer 3

set
\[2(x-\frac{\pi}{3})=0\] and
\[2(x-\frac{\pi}{3})=4\pi\] and solve both for \(x\) would be one way to do it

Answer 4

Thank you @satellite73
