y=a(b/c)^x
It's the apocalypse, everyone dies really quickly and that's exponential decay, you got it.

Exponential Growth Graphs

the equation for the graph is 1(2)^x
1 is the vertical intercept
(2) is the multiplying factor and ^x is the amount of times you repeat the equation.

The graph doubles at each point

y = 1(2)^x

Exponential Growth Equations

Exponential growth equations represent exponential growth: situations where the increase is not steady, like linear graphs, but instead is more of a curve.

Example equation:

y= 20(2)^x

The 20 in the equation represents the starting value, whereas the two represents the growth rate (the amount it grows by)

Exponential Growth Tables

Exponential growth tables is when the graph lines begins to go up with a curved line.

Another thing is on the table the numbers go up which gives the graph line the positive growth

The y value when x is at 0 is the y-intercept or the starting value

Instructions

Your group will come up with different ideas for what makes these models different.

Steps:
1. Click on three dots
2. Click on edit
3. If you want to put in a picture, click on the magnifying glass

Ideas:
1. Insert image and describe what is happening
2. Insert equation and describe the different parts
3. Insert table and describe what is happening.

Exponential Decay Equations

Decay happens when the multiplier of an equation is less than 1(sorry to the person who typed that in before, I accidentally typed over your progress).
For example: a = 10(1/2)x,
y= 20(2/3)x
