Question

write equation cosine function with amplitude of 4, phase sift right 60 degrees, period shift 720 degress and reflected x axis

Answer 1

Solution:

Given a cosine function of the form:

$\begin{gathered} y=A\cos(Bx) \\ where \\ A\Rightarrow amplitude \\ \frac{2\pi}{|B|}\Rightarrow period \end{gathered}$

Given that the function has a amplitude of 4, phase sift right 60 degrees, period shift 720 degress and reflected x axis, this implies that
