Answer:
(2)
Step-by-step explanation:
Let f(x) = y → f-¹(x) = f(y) = x, f(y) is the inverse of f(x)
Thus,
=> -x³ - 9 = y
=> - y - 9 = x³
=> (-y - 9)^(1/3) = x
=> f(y) = x
Inverse is (-y-9)^(1/3)
Replacing the variable, inverse is (-x-9)^(1/3)
Option (2)
Answer:
A. 131deg
B. 49deg
C. 131deg
Step-by-step explanation:

Opposite congruent angles are equal
-5/16 is less than -3/8
-5/16 is greater than -11/32
-5/16 is less than -1/4
5/16 is less than -1/8
1 bag = 15 p
1.065p each day
7 days = 1.065 * 7= 7.45
15-7.45=7.54
