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!
Can you fill in the blanks?For exponential growth,
the ______ the base, the _______ it grows.
lower or higher faster or slower
Which is decaying the fastest?
y = (½)x y = (¾)x
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!
Which function is growing the fastest?
y = 4x y = (½)x y = 8x
? ? ?
How can you tell?
Which function is growing the fastest?
y = 4x y = (½)x y = 8x
How can you tell?
It has the highest base!
Which function decaying the fastest?
Remember to look at when x = -1 and x = 0!
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!
