Piecewise Functions
The piecewise function represents the monthly sales of Jenny's boutique.
It's required to find the monthly sales when Jenny first started to track the sales.
It happened when x = 0, so we need to know which piece to use.
The only part of the function that includes x = 0 is the first one, thus:
[tex]\begin{gathered} f(0)=4,000(1.1)^0 \\ f(0)=4,000\cdot1 \\ f(0)=4,000 \end{gathered}[/tex]
Choice: A) $4,000
