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.

Im pretty sure it's D so Lets hope it is
Answer:
54 feet
Step-by-step explanation:
We can use proportions
1 inch 27 inches
--------- = ------------
2 feet x feet
Using cross products
1x = 54
The building is 54 feet
The solution would
be like this for this specific problem:
(cos^2x-1)/cosx+1
cos^2x-1= (cosx+1)(cosx-1)
cosx-1

Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
What we know:
slope: -1
y-intercept: 0.7
Therefore:
m = -1
b = 0.7
Plug the values of <em>m </em>and <em>b </em>in y = mx + b:
y = -1x + 0.7
OR
y = -x + 0.7
OR
y = 0.7 - x
^^^These are all written in slope intercept form but just in different ways
Hope this helped!
