3.03 Key Features of Exponential Functions Question 1: The average price for a new car is $30,000. Each year, the value of that car decreases by 15%. The function to represent this situation looks like this: f(x) = 30,000(0.85)x a) What is the y-intercept? What does that represent? b) You decide to stop checking the value of the car after it hits $15,000. What is a reasonable domain to represent this decrease in value? c) Find the average rate of change of the function f(x) from x = 4 to x = 9.

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
