W Q 5. Consider the function A(x) = 3(0.75) to answer the following questions. Part A - From just looking at the equation of the function, would you expect the average rate of change for this function to be positive or negative? Explain your reasoning. Part B - Find the average rate of change on the interval [-1, 1]. Show all of your work. B i U Font FamilyQ 3. At what point does the exponential function overtake the linear function on the interval (0,co)? [Type your answer as an ordered pair with no spaces.] Ax) = 3* 8 (x) =2x+6 W 4. Jax is running a marathon and plans to pace himself by running 9 miles per hour. Write an equation to represent the distance, d, Jax will have traveled after running for h hours. O h= 9d Oh=7 O O d= 9hW Q 2. Which of these is not like the other? Explain. Option 1:8(x) = 1 Option 2: x - 3 {(0,0.4), (1,0.8), (2, 1.6), (3,3.2), (4,6.4)} Option 3: Option 4: Ax) = -3(2.9)* O Option 2 because it is a continuous function where as the rest of the functions are discrete. O Option 4 because it has a y-intercept at (0,-3). Option 1 because it is neither linear nor exponential and the rest of the options are. O Option 3 because it is an exponential function where as the other options are linear functions
