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:
The answer is $48
Step-by-step explanation:
48x15=720
A = bh/2
A = 33 x h / 2
528 = 33h / 2
33h = 1056
h = 32cm
Start with parentheses first
Afterwards do exponents
Next do either multiplication or division (L to R)
Then Addition and Subtraction (L to R)
