An art collector has accumulated many pieces of art over the years. Some increase in value, and unfortunately some also decrease in value.
The value of one piece of art over the last 20 years can be represented by the
function y = where y is the value of the piece in 100's of dollars, and is
the number of years since purchasing the work.
Is the artwork increasing or decreasing in value?
What is the percent change in the value?
What was the original value of the piece of art?
What will the value be after 17 years? Round to the nearest dollar.
