Well, the exponential function is the initial price of that at t=0 is 3,500, as we can see in the chart. Then, the function becomesLet to see in t=2, where the price is g=2000:Taking the natural logarithm:Thus, the difference between t=0 and t=2 isAnd then we get the change of x in one year equal to 0.035.Thus, the end of the equation isYou can insert any t and see that it is correct, for example, t=7
