1. Graphing

1.1. Parent Function

1.1.1. b^x Notes from 3/5

1.2. Growth vs Decay

1.2.1. b<1 = decay and b>1 is growth Notes from 3/5

1.3. Asymptote

1.3.1. is k and is horizontal notes from 3/5

1.4. Transformations and Flips

1.4.1. f(x) = ab^(cx-h)+k notes from 3/5

1.4.2. a is vertical flip

1.4.3. c is horizontal flip

1.4.4. h is left and right

1.4.5. k is up and down

2. Solving Exponents without logs

2.1. Change to common base

2.1.1. solve using exponents of bases to find x paper notes from 3/13 & quiz of Intro to logs same base and equal means exponents are equal

3. Logs

3.1. Definition

3.1.1. the exponent that I must take the base to in order to get the arguement notes from 3/14

3.2. parts of a log

3.2.1. log(base as subscript)(argument) "log base _ of _ is _" notes from 3/14

3.3. without calculator

3.3.1. make it base to the x power equals the argument exponent chart notes from 3/14

3.4. with calculator

3.4.1. hit math alpha math then plug in base and argument

4. More equations with logs

4.1. logbx = y -> b^y=x

4.1.1. Paper notes from 3/15

4.2. Isolate base

4.2.1. inverse operations to cancel out PEMDAS paper notes 3/15

4.3. use logs

4.3.1. if exponent is equation, find the log that it will be equal to paper notes 3/15

5. Applications

5.1. half life

5.1.1. how long it takes the thing to half P=P0(.5)^t/h packet notes 3/21 P0 is starting amount and t is time passed and h is half life

5.2. Exponential model: ab^x

5.2.1. a= starting value

5.2.2. b=growth/decay factor Notes from 3/19 growth = 1 + r & decay = 1 - r

5.2.3. x = time passed

5.3. Continuous

5.3.1. change exponentially at a continuous rate P=P0e^rt packet notes 3/21 P0 is starting point and e is Euler's number and r is growth/decay rate and t is time passed
