This is an example of a piecewise defined function. It means that the function has not a unique formula to represent it, but it depends on "where" you want to compute it.
So, if you choose any input , you have two alternative:
- If (i.e., if you've chosen any input that is not 3), the output will be the opposite of the input you've chosen ()
- If , the ouput will be -1.
So, let's forget about for a moment. For any input you choose, the answer is . The graph of this function is the bisector of the second and fourth quadrant.
Now remember that there is our special case: you have to "carve a hole" in our line, at , and assing to this point the value -1, instead of what we would expect, i.e. -3.
So, the graph of this function is the line , except for one point (), where we reassign the value to be -1.

Answer:
Step-by-step explanation:
Number of clips in box A = 40
Number of clips in box B = 23
If Sally took out 6 clips from each box
Remaining clips in box A = 40 - 6 = 34 which is twice of 17
Remaining clips in box B = 23 - 6 = 17
Answer:
There are 12 less people than before 2:30
Step-by-step explanation:
Before 2:30 ..... x
At 2:30 ..... x-12+2 = x-10
After 2:30..... x-10 -2 = x-12
