Answer:
Option 3 - f(x)= 4x, 
Step-by-step explanation:
To find : Which two functions are inverses of each other?
Solution :
Two functions are inverse if 
Now, we find one by one
1) f(x)= x, g(x) = -x
Not true.
2) f(x)= 2x, 
Not true.
3) f(x)= 4x,
i.e. is true.
So, These two functions are inverse of each other.
4) f(x)= -8x, 
Not true.
Therefore, Option 3 is correct.
Answer:
3 times
Step-by-step explanation:
The lowest common multiple of 3, 8, and 12 is 24.
Therefore they all hoot together at the 24th hour, 48th(24×2) hour, 72nd(24×3)hour. making 3 times before the 80th hour
ANSWER
or
EXPLANATION
We want to find the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4).
The point-slope form is given by;
where
is the slope of the line.
If
The point-slope form is
On the other hand, if
Then the point-slope form is,
These two equations are the same when simplified.
A reciprocal just flips the fraction
1. 
2.
3. Before it is flipped it is 
but it turns into 
Hope this helps!
4 to the fourth power is the same as
4×4×4×4=256
I hope I've helped!
