Answer:
Step-by-step explantion:
Definition of absolute value of x:
|x|=x assuming x has taken a positive value.
|x|=-x assuming x has taken a negative value.
|x|=0 assuming x is 0.
----------------------------------------------------------------------------
Add on both sides:
Let .
Assume x is positive, then where is positive since is positive. Also for positive x.
Assume is negative, then .
Assume , then .
The result for h is positive when x is positive but 0 elsewhere for x.

Answer:
C
Step-by-step explanation:
Switch the X and Y values in each point from the f(x) function to its inverse g(x).
Step-by-step explanation:
the answer is 4 m + 5 and my workings and the image above
It’s the first option.
5.85/6.5= 0.90
Answer:
So g(6) comes out to be 2.
Step-by-step explanation:
So f(6)=5 means when f acts on 6, the result is 5....so the inverse would take 5 back to 6...or g(5)=6
So f(2)=6 means that f reassigns 2 to 6....so the inverse would take 6 back to 2....or g(6)=2
hope this helps :)
