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.
I hope this helps! :)
BD is 18

7 x 24 = 168 hours a week
168 x 60 = 10,080 minutes a week
10,080 x 60 = 604,800 seconds in a week
