Answer:
a. The amplitude should be 2.
The period should be 2\pi.
b. maximum value occurs in (0,1) at x = 0
minimum value occurs in (pi,-1) at x = pi
Step-by-step explanation:
To solve this problem just do the following,
x+9=-12
-9 -9
x=-21
Check
-21+9=-12 = True

Answer: -89
Step-by-step explanation:
So your equation is
- 9(a) - 7(x) - 9(c) - 9(b) - 7(y)
You know that (a) (b) and (c) = -1
You also know that (x) and (y) = 7
So, when you put this into the equation, it will look like this:
- 9(-1) - 7(7) - 9(-1) - 9(-1) - 7(7)
When you work that out you will get left with your answer, which is -89.
