A piecewise-defined function changes the formula or its value at one or more points of the domain. In your case, the function will be a series of steps. You do not say if the stock gains steadily during odd months or increases abruptly at the end of the month, and similarly falls steadily of abuptly in even months. If the value changes suddenly, it would not be a continuous function. Let's assume its value stays constant during each month and changes at the end of that month. In that case:
For month 1, the value is 2000.00
During month 2, the value is
2000. x 1.2 = 2400.00
During month 3, the value is
2400.00 x (0.85) = 2040.00
During month 4, the value is
2040 x (1.2) = 2448.00
Try to express those values in terms of n.
on december31, 1995, paul invested $2000 in a stock. his stocker gains 20% ever odd month (jan, march, may..) and loses 15% every even month (feb, april, june...)
it says write a piecewise defined function for the value of the stocker n months after the original investment, n is a whole number.
how do i write a piecewise function?
