help mee?

i really d know

okay thanks though

@georgia545 @aloud
Do you know the range of f(x)?

0??

|dw:1434724687580:dw|

So the range of y=cos(x) is [-1,1]
Are you familiar with the interval notation?

noo

oh yeah i do i just didnt know that was the name

range of y=[-1,1] means the range of y can take any value between -1 and +1.

(5,-5)?

Yes, [-5,5] is the correct new range.

So which answer would it be because in f(x) it was [1,-1] to [5,-5] but thats not an option

so it would be a because it went from [1,-1] and shifted down 3 right?

It won't be A. Try again. :)

Did you say [-1,1] translated down?
Recall we have g(x)=-5cos(x)-3.

We agreed it was [-5,5] before translation, didn't we?

i thought it started as [1,-1] in f(x) then went to [5,-5] in g(x) ????

The range of function g(x) is [5,-5]. Then it is shifted down 3 units in the negative y direction.

Then the range also changes according to it.
