Answer
D. Verifying
Step-by-step explanation:
The transformation set of 
values for function 
is ![[-1,1]](https://tex.z-dn.net/?f=%5B-1%2C1%5D)
this is an interval to which sine function maps.
You can observe that the interval to which 
function maps equals to ![[-2,0]](https://tex.z-dn.net/?f=%5B-2%2C0%5D)
.
So let us take a look at the possible options.
Option A states that shifting up by 
would result in having an interval ![[-1,1]+\frac{\pi}{2}\approx[0.57,2.57]](https://tex.z-dn.net/?f=%5B-1%2C1%5D%2B%5Cfrac%7B%5Cpi%7D%7B2%7D%5Capprox%5B0.57%2C2.57%5D)
which is clearly not true that means A is false.
Let's try option B. Shifting down by 
to get would mean that has a transformation interval of ![[-1,1]-1=[-2,0]](https://tex.z-dn.net/?f=%5B-1%2C1%5D-1%3D%5B-2%2C0%5D)
. This seems to fit our observation and it is correct.
So the answer would be B. If we shift down by one we get , which means that 
and 
.

Answer: n=9
Step-by-step explanation:
5n-12=3n+6
move 12 to the other side
5n=3n+18
then move 3n to the other side
2n=18
n=9
