Answer:
The inverse is 
(x) = 
Step-by-step explanation:
(By the way, (x) is f negative one of x, like f(x), but inverse)
f(x) = 
- 4 is the same as y = - 4
y = - 4 start with the equation.
x = 
- 4 switch x and y.
x + 4 = add 4 to both sides.
= y square both sides.
(x) = change y to the inverse f(x) format.

Answer:
10°
Step-by-step explanation:
