Question

functional periods

Answer 1

y=-3 cos1/4x

Answer 2

so the question is

\[y = -3\cos(\frac{1}{4}x)\]

Answer 3

yes c:

Answer 4

ok... so to find the period you need to use

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

in the question you posted

b = 1/4

so the period is

\[period = \frac{2\pi}{\frac{1}{4}}\]

you just need to simplify it

Answer 5

to do that dont i just multiply the whole thing by 1/4?

Answer 6

well when you divide by a fraction flip it and them multiply

so its

\[\frac{2\pi}{1} \times \frac{4}{1} = \]

Answer 7

8pi

Answer 8

thats it
