Question

what is the amplitude period phase shift of f(x)= -3cos(4x +pi) + 6

Answer 1

@mathmate

Answer 2

Do you know how to graph y=cos(x)?

Answer 3

not really

Answer 4

In the standard form of
f(x)=a*cos(b(x-h))+k
the period is
\[\frac{2\pi}{|b|}\]
phase shift is h, and amplitude is a.

If you would transform the given function into its standard from, you can read off these parameters.

Answer 5

tbh today is the last day of school and im rushing to finish everything before 11:59

Answer 6

is there like a really fast way to learn this

Answer 7

\(\large f(x)= -{\color{blue}{ 3}}cos({\color{brown}{ 4}}x +{\color{olive}{ \pi}}) + 6\qquad
\begin{array}{llll}
{\color{blue}{ amplitude}}\\
\textit{phase shift}=\cfrac{{\color{olive}{ \square }}}{{\color{brown}{ \square }}}\\
\textit{period}=\cfrac{2\pi}{{\color{brown}{ \square }}}
\end{array}\)

Answer 8

:)

Answer 9

ooh ok now i put them in fractions?

Answer 10

helloooo

Answer 11

well you'd just use the values given in the function, to get the amplitude, phase shift and perod
