The description is exponential decay because, "... at the start of the year."

Loss of 10% means keeping 90%.

v=600000%2A%280.9%29%5Et, but if depreciation happens at the start, not simply after each year, then make this equation highlight%28v=600000%280.9%29%5E%28t%2B1%29%29. This makes the value begin its mathematical depreciation immediately.
