Periodic function is a special type of function in which, function returning to the same value at regular intervals.
here cos(3x + 5) + 7 is a periodic function and we have to find its period.
we know, period of cosx = 2π
and period of cosax = 2π/|a|
so, period of cos3x = 2π/3
or, period of cos(3x + 5) = 2π/3
or, period of cos(3x + 5) + 7 = 2π/3
hence, period of cos(3x + 5) + 7 is 2π
