Unit 3 Lesson 3Review of Lesson 3-Compare rates

Page 2: Comparing Exponential Growth and Decay

Can you fill in the blanks?For exponential growth,

the ______ the base, the _______ it grows.

lower or higher faster or slower

Click on to the next slide for the answer!

Page 3: Comparing Exponential Growth and Decay

Can you fill in the blanks?For exponential growth,

the ______ the base, the _______ it grows.

lower or higher faster or slower

Page 4: Comparing Exponential Growth and Decay

Which is decaying the fastest?

y = (½)x y = (¾)x

Page 5: Comparing Exponential Growth and Decay

Which is decaying the fastest?

y = (½)x y = (¾)x

½ = 50% ¾ = 75%

100%-50% 100%-75%

Decay is 50% 25%Most decay!

Page 6: Comparing Exponential Growth and Decay

Which function is growing the fastest?

y = 4x y = (½)x y = 8x

? ? ?

How can you tell?

Page 7: Comparing Exponential Growth and Decay

Which function is growing the fastest?

y = 4x y = (½)x y = 8x

How can you tell?

It has the highest base!

Page 8: Comparing Exponential Growth and Decay

Which function decaying the fastest?

Remember to look at when x = -1 and x = 0!

Page 9: Comparing Exponential Growth and Decay

Which function decaying the fastest?

Decrease is from 10 to 5

Decrease is from 3 to 1

Great job with our last lesson!

Thank you for working very hard in this Unit 3!
