Question

Find the period of..

Answer 1

trigonometry is during 4th period...:)

Answer 2

\[-3 \cos (x + \pi) - 7\]

Answer 3

Lool. ;-;

Answer 4

the -3 only changes the affects the amplitude
the -7 only shifts the whole graph down
the + pi only shifts the graph horizontally.

the expression should therefore still have the same period as y = cos x... what's the period of cos x?

Answer 5

you lost me. ;c

Answer 6

2pi... is the period...
i think i may have lost myself...:( lemme double check...

Answer 7

That's correct, Dpainc.

Answer 8

what @dpaInc is trying to say is that only multiplying the (x) will change the period of the graph

Answer 9

thanks... @SmoothMath .... :)

But how'd you guys get that o;
