Piecewise Function
We are given the piecewise function shown in the figure.
We are required to calculate g(4) - 3g(3).
First, we calculate g(4). Since 4 is greater than 3, we use the second function:
Now we need to calculate g(3). We use the same function because 3 is greater or equal to 3:
Now we calculate:
g(4) - 3g(3) = 273 - 3*90 = 273 - 270 = 3
Answer: 3
