how do I use a graphing calculator for this?

EXPLANATION First, we find the initial value. It occurs when O years have passed. So, we let t=O and compute v (0). v (0) =25,900(0.76) = 25,900(1) = 25,900 The initial value was $25,900. Next, we find the value after 11 years. We let t= 11 and use the calculator to compute v(11). v (11) =25,900(0.76)'! = 1265.4... Rounding to the nearest dollar, we get $1265. ANSWER Initial value: $25,900 Value after 11 years: $1265
