1 What is the initial value of the function y = 7(3)x?

1 7 Home

Write a Now-Next Rule for y = 2•5x

2 START = 2, NEXT = NOW•5 Home

3 This is a _______ sequence with a common _______. Given the sequence, fill in the blanks: 1, 4, 16, 64, … This is a _______ sequence with a common _______.

Geometric sequence, common ratio 3 Geometric sequence, common ratio Home

4 Suppose a printing press is worth $120,000 and it increases in value by 15% each year. Write an equation y = to represent this exponential function.

4 y = 120000(1.15)x or y=120000(1+.15) x Home

5 Suppose a brand new car is purchased for $29,000 and it decreases in value by 8% each year. Write an equation y = to represent this exponential function.

5 y = 120000(.92)x or y=120000(1-.08) x Home

What is the common ratio of the function y = 7(3)x? 6 What is the common ratio of the function y = 7(3)x?

6 3 Home

7 If the population of snakes is represented by the equation y = 300(2)x where x = # of months, y = total amount of snakes. How many snakes will there be in 3 months?

7 2400 snakes Home

8 In the list below, which one of the following term does NOT belong to the rest? ~Exponential Function ~Geometric Sequence ~y = a(b)x ~NEXT = NOW + 5 ~ “J” shaped graph

8 NEXT = NOW + 5 Home

9 If you have the original function y=2x and the new function is y = 2x + 5, compare the y-intercepts.

Original y-intercept is 1 and the new y-intercept is 5 9 Original y-intercept is 1 and the new y-intercept is 5 Home
