Question

find periods for given functions
cos(3x+5)+7​

Answer 1

Answer:

period of given function=  2π/3

Step-by-step explanation:

Period of a normal cosine function is 2π

Answer 2

Answer:

$★ \large\underline{\underline{\bf\red{3X + 5 \: \: is \: \: \frac{2\pi}{3} }}}$

Step-by-step explanation:

if period of f(x)=t

then period of f( ax+d)= t/a

thus period of cos x = 2π

then period of cos(3x+5) is 2π/3
