Answer:
No real solutions.
10
using the second equation you can get s=-2. then plugging that into the first you get
-9(-2)-8 = 18-8 = 10
Answer:
The required range of the function is [-7,-1]
Step-by-step explanation:
Given : Function
To find : What is the range of the given function?
Solution :
The range is defined as the variation in which any function is defined.
We know that the sin function lies between [-1,1]
.....(1)
The required function is
Multiply equation (1) by -3
.....(2)
Now, we subtract equation (2) by 4
Therefore, The required range of the function is [-7,-1].
