Answer:
A. 4
Step-by-step explanation:
We can look at the number line and find B and A
we get
B=-7
A=3
now, we can find |B| and |A|


now, we can find
|B|-|A|
now, we can plug values


So,
option-A

Answer: 
Step-by-step explanation:
Least Common Multiple :The least positive number that is a multiple of two or more numbers.
To find : The least common multiple of:
and 
Since, 

The least common multiple of:
and
=
[take highest power of x and y ]
Hence, the least common multiple of:
and
= 
F(x) = 3x + 2x = 3f-1(x) + 2x - 2 = 3f-1(x)(x - 2)/3 = f-1(x)(14 - 2)/3 = f-1(14)12/3 = f-1(14)4 = f-1(14) f(f-1(14)) = f(4)f(4) = 3(4) + 2f(4) = 12 + 2f(4) = 14 A function and its inverse are inverse operations, like addition and subtraction. They undo each other. f(f-1(x) = x
