Answer:


Domain: All real numbers
![Range = [-1,1]](https://tex.z-dn.net/?f=Range%20%3D%20%5B-1%2C1%5D)
Step-by-step explanation:
Given
The attached graph
Solving (a): f(0)
On the attached graph
when 
So:

Solving (b): f(pi)
On the attached graph
when 
So:

Solving (c): Domain
There is no restriction on x.
Hence, the domain is the set of all real numbers
Solving (d): Range
In the attached graph


So, the range is:
![Range = [-1,1]](https://tex.z-dn.net/?f=Range%20%3D%20%5B-1%2C1%5D)
Answer:
no real numbers will make this equation true
Step-by-step explanation:
if you square both sides, you'll get sqrt(-49). this will get you an imaginary number (7i) which is not a real number.
