Find the exact value of.

( - )

Step-by-step explanation:

Using the trigonometric identity

cos(a + b) = cosacosb - sinasinb

Note = + , thus

cos ( )

= cos( + )

= cos ( ) cos ) - sin (

= ( × ) - (

= -

= ( - )

there are no figures how am i supposed to answer this question

step-by-step explanation:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
