Question

Good morning yall quick question Alg 2

Answer 1

The last 2 options are
\[4\cos(x - \frac{ \pi }{ 2 })\]
\[-4\cos(x - \frac{ \pi }{ 2 })\]

Answer 2

@IrishBoy123 Can you help

Answer 3

if you want to figure it out yourself, just set x = 0 and \(x = \pi /2\) and see which fits

it has to be one of he last two because setting x = 0 clearly rules out the sin ones

Answer 4

it is C correct? @IrishBoy123 i need this right please :)

Answer 5

have a look at d

\(-4\cos(\pi/2 - \pi/2) = - 4 \cos 0 = -4\)

make sure you are happy with answer!

Answer 6

Thank you <3 i have 1 more if it is fine ;)
