You subtract 582,295 from 670,063 and you get 87,768 so 87,768 fewer people attended the pacers game.
Answer:
She estiamted the amount.
No she is not correct, she is incorrect. The correct answer would be that they would pay $38.40 for the item.
Step-by-step explanation:
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.
7 * 2.9
(7 * 2) + (7 * 0.9) = 20.3 <==
