Considering that the function f(x) is a step function, the value of f(0) is -2
The given parameters are:
Using the above segments, we have the following table of values
x   y
-5 Â 3
-4 Â 2
-3 Â Â 1
-2 Â Â 0
-1 Â Â -1
0 Â Â -2
1 Â Â Â -3
2 Â Â -4
In the above table, we have:
x    y
0 Â Â -2
This means that:
f(0) = -2
Hence, the value of f(0) is -2
