Equations of Exponential Functions

Arnold dropped a ball during an activity and recorded its height in the given table. Write a rule in the form of y = ab^x (not "x-1" exponent) that represents his data. When finished add your a and b values together. What is the sum?

A major technology company, ExpoGrow, is growing incredibly fast. The latest prospectus (a report on the company) said that so far, the number of employees, y, could be found with the equation y = 3(4)^x , where x represents the number of years since the company was founded. How many people founded the company? How can the growth of this company be described?

• # Founded = 4, Multiplier = 3

• # Founded = 3, Multiplier = 4

• # Founded = 3/4, Multiplier = 4

• # Founded = 4, Multiplier = x

As part of a major scandal, it was discovered that several statements in the prospectus for ExpoGrow were false. If the company actually had five founders and doubles in size each year, what rule should it have printed in its report?

• y = 5(2)^x-1

• y = 5(2)^x

• y = 10(2)^x-1

• y = 2(5)^x-1

• None of these

A computer virus is affecting a lab in such a way that each day, a certain portion of virus-free computers is infected as recorded in the given table. How many computers are there? What portion of virus-free computers is infected each day? How many computers will remain virus-free at the end of the third day?

• Comps = 27, Infection = 1/3, Day 3 = 8

• Comps = 27, Infection = 3/2, Day 3 = 8

• Comps = 27, Infection = 1/3, Day 3 = 19

Most of the exponential equations you have used in this chapter have been in the form y = ab^x . How can you identify a using a table?

• It is the y-value when x = 0

• It is the x-value when y = 0

• It is where the x- and y-values are the same

• It is the value that y-values get very close to but never equal

• The amount the y-values increase by each time.

• The first number in the word problem.

• The starting value when no time has passed.
