65) f (x) = x+3 65) x + 8 Solve the problem. 66) Given that the domain of a one-to-one function f is [-6, 1) and the range of f 66) is (-9, 00), state the domain and range off-. Identify the parent function. List the sequence of transformations, in the correct order, to obtain the graph of function g. 67) 8(x) =- 7V/x - 4.5 + 6.6 67) Solve the equation. 68) 4(3x + 3)_ 1 (x-9) 164 68) Solve the problem. 69) The atmospheric pressure on an object decreases as altitude increases. If a is the 69) height (in km) above sea level, then the pressure P(a) (in mmHg) is approximated by P(a) = 760e-0.13a. Determine the atmospheric pressure at 5.458 km. Round to the nearest whole unit. Solve the equation. 70) log, (64x) - log, (x + 77) = 3 70) Solve the problem. 71) The population of a country on January 1, 2000, is 13.7 million and on January 1, 71) 2010, it has risen to 15.8 million. Write a function of the form P(1) = Poet to model the population P(t) (in millions) z years after January 1, 2000. Then use the model to predict the population of the country on January 1, 2012. Round to the nearest hundred thousand. 72) A veterinarian depreciates a $10,000 X-ray machine. He estimates that the resale 72) value V(t) (in $) after t years is 80% of its value from the previous year. Therefore, the resale value can be approximated by V(1) - 10,000(0.8)'. a. Find the resale value after 3 yr. b. If the veterinarian wants to sell his practice 8 yr after the X-ray machine was purchased, how much is the machine worth? Round to the nearest $100
