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:
Use the equation 250+25w=400+20w
Step-by-step explanation:
Replace w with one of the answers until you get the right one.
pretty sure its 35 but I don't have a calculator with me so double check
Answer:
im not sure the answer tho- just trying
