The value of a truck can be modeled by the function V(t) = 16,000(0.76)t, where t is the number of years since the car was purchased. To the nearest tenth of a percent, what is the monthly rate of depreciation? Unit 3 Practice Simplify Solve Solve Sr-85 is used in bone scans. It has a half-life of 64.9 hours. Write the exponential function for a 12 mg sample. Find the amount remaining after 72 hours. Show work algebraically. Write exponential function given (2, 18.25) and (5, 60.75). Show your work algebraically. A 4 feet tall grows 3 percent each year. How tall will the tree be at the end of 12 years? Round your answer to the hundredths place. A BMX bike purchased in 1990 and valued at $6000 depreciates 7% each year. a next-now formula for the situation an explicit formula for the situation How much will the BMX bike be worth in 2006? In what year will the BMX bike be worth $3000? Day 9: Transformations of Graphs…kf(x) and f(kx) Transformations Warm-Up Day 9: How are the following graphs changed from their parent graph, F(x) = x2? (If you don’t remember some of the transformations, graph the transformed equation and the parent equation in the calculator ) – 1) F(x) = (x 4)2 5) F(x) = 4x2 2) F(x) = x2 – 4 6) F(x) = ½ x2 3) F(x) = x2 + 1 7) F(x) = 3(x - 4)2 4) F(x) = (x + 3)2 8) F(x) = 1/4 x2 + 3
