Algebra IAnswered question
Belinda is thinking about buying a car for $18,500. The table below shows the projected value of two different cars for three years:
Number of years 1 2 3 Car 1 (value in dollars) 17,390 16,346.60 15,365.80 Car 2 (value in dollars) 17,500 16,500 15,500
Part A: What type of function, linear or exponential, can be used to describe the value of each of the cars after a fixed number of years? Explain your answer. (2 points)
Part B: Write one function for each car to describe the value of the car f(x), in dollars, after x years. (4 points)
Part C: Belinda wants to purchase a car that would have the greatest value in nine years. Will there be any significant difference in the value of either car after nine years? Explain your answer, and show the value of each car after nine years. (4 points)

Solving equations with radicals and rational exponents is encountered in Algebra 1 level, which makes a study of exponents relatively difficult without good examples that start with an analysis of variables and mathematical objectives. Remember to start with the use of the radical sign and focus on those multiplications that are being repeated. It is much easier to focus on answers that have been provided to determine all the surds and related numbers. Take your time to post your questions and see how similar problems have been resolved.
