Practice #1 What is the exponential function that represer riana Grande's concert has been sold out for weeks nd the cost of a ticket increases as the date of the oncert draws closer. If the original price of a ticket is 239.00, how much will the ticket cost in 5 days if it ncreases at a rate of 20% a day? situation? Solve. What is the final answer? What do we know? Fill in this side growth or decay? initial amount (a) rate (r) growth or decay factor (b) input value (x)

A model rocket is launched into the air from the top of the building. The table models the vertical height, y, in feet, for a given time, x, in seconds. What type of function would best model the data and why?

Utah, the land of milk and honey where math students have courage and freedom rings true, is one of the fastest growing states in America. The state population was 2.942 million people in the year 2014, and 3.167 million people in the year 2018. For the prompts below, you may approximate this as an exponential function with a constant growth rate. What is the annual percentage growth rate between 2014 and 2018, rounded to two decimals? Growth Rate = % At the current growth rate, what is the expected state population in the year 2037, rounded to two decimals? Expected Population of Utah in 2037 million people = At the current growth rate, in what year is the population expected to reach 4.2 million people? Assume that the population figures above are measured at the beginning of each year. Your answer should be a whole number. Utah expects to reach 4.2 million people in the year:

Identify each function or situation as an example of exponential growth or decay. What is the y-intercept? 1. a. y = 3(4*) b. y = 11(0.75") c. You put $2000 into a college savings account for four years. The account pays 6% interest annually.
