The exponential decay graph shows the expected depreciation for a new boat, selling for $3500, over 10 years a. write an exponential function for the graph. b. use the function in part a to find the value of the boat after 9.5 years. pease explain this step by step.

Part a: the formular for the exponential decay of a function is given bywhere f(t) is the value of the function after time t, is the initial value of the function (i.e. the value of the function at time t = 0), k is the decay constant and t is the time passed.given the graph showing the expected depreciation for a new boat, selling for $3500, over 10 years.thus, .from the graph, the value of the boat after 2 years is $2,000, thus we havetherefore, the exponential function for the graph is given bypart b: the value of the boat after 9.5 years is given bytherefore, the value of the boat after 9.5 years is $245.27
