Absolute value of
Step 1
We need to solve the absolute value inequality.
Step 2
Firstly we discuss the rules of absolute value inequalities.
Here the steps :
Step 1: Isolate the absolute value on left hand side.
Step 2: Remove the absolute value sign.
Step 3: For greater than sign:
Quantity inside the absolute value < - (Number on other side)
OR
Quantity inside the absolute value > (Number on other side)
Step 3
Or
Step 4
So, final answer is:
Or
Answer is given below (on video)
For each of the piecewise-defined functions, determine whether or not the function is one-to-one, and if it is, determine its inverse function.
