Linear Growth
Occurs when a quantity grows by the same absolute amount in each unit of time
Exponential growth
Occurs when a quantity grows by the same relative (or percentage) amount in each unit of time.
Linear Growth & Decay
Occurs when a quantity grows by the same absolute amount in each unit of time.
Constant: The amount of change.
Example: A savings account that earns 50 dollars in interest each month.
Formula: Can be represented as y = mx + b, where m is the constant absolute change.
Linear growth & Decay
F(x)=mx+b

Doubling
Exponential growth
Linear Decay
Occurs when a quantity decreases by the same absolute amount in each unit of time.
Constant: The amount of change is a negative value (-m).
Example: A car depreciating by 500 dollars each year.
Formula: Can also be represented as y = mx + b, where m is the constant absolute change (negative for decay).
Exponential Decay
Occurs when a quantity decreases by the same relative (or percentage) amount in each unit of time.
Example: The amount of a radioactive substance decreasing by half every X years (half-life).
Formula: Can be represented as A(t) = P(1 - r)^t, where P is the initial amount, r is the decay rate (as a decimal), and t is time.
General Formula for Exponential Growth/Decay
A(t) = P(1 \pm r)^t
A(t) is the amount after time t.
P is the initial amount (principal).
r is the growth/decay rate (as a decimal).
t is the time.
Use (1 + r) for growth and (1 - r) for decay.
