Question

how do i find period: y=sin(5x +11\pi) -4

Answer 1

the coefficient of x is used to find the period

given

y = asin(bx)

a= amplitude and the period is

\[period = \frac{2\pi}{b}\]

the phase shift is \[\frac{11}{\pi}\]

and the whole graph is moved down to centre on y = -4

hope it helps
