find the period of the function f(x)=cos(3x+5)+7
2π/3
if period of f(x)=t
then period of f( ax+d)= t/a
thus period of cos x = 2pi
then period of cos(3x+5) is 2pi/3
Pls approve my answer by clicking on yes below!!!!!!!!!
Dear student,The period of the given function is the period of cos(3x+5) itself, as 7 is a constant and doesnt influence the period,....and the period of cos(ax+b) is 2pie/a,...so the answer is 2pie/3 :)THANKS and ALL THE BEST
