There are no expressions shown but I will show you what it would look like! 2(x)-8 would be the best answer!
ANSWER
Frequency=2
Midline =3
Amplitude =5
Period =π
EXPLANATION
We have:

The given function is of the form;

where
a=|5| =5 is the amplitude
and b=2 is the frequency.
and 2π/b=2π/2=π
The range of the given function is
8≤y≤-2
The midline is

Answer:
Use keep change flip And narrow down to a simplest anwser
2 = r(4)
To find r, you've gotta divide it out.
2/4 = r/4
1/2 or 0.5 = r
c=(0.5)t
