Graphing Expo Growth - Decay
Graphing Exponential Growth/Decay.
Step 1. Create the Parent Graph
Step 2. Find (Identify) A, H, K
Step 3. Create your new T-Chart
Domain - All real #'s
Range - y>k when a is positive, while y<k when a is negative
Asymptote - y = k
Step 4. Draw Asymptote
Step 5. Graph new points
Exponential Formula: y=axbx-h +k
a= multiplier
a>1 = stretch
0<a<1 = compression
a<0(negative) = flipped over x-axis
b = base
b>1 = while #'s growth, always increasing\
0<b<1 = fraction ; decay , always decreasing
B is never negative only the multiplier is
h = lf/rt: opposite
k = up/dw

Compound Interest Formula
A=P(1+ r/n)nt:
A: Amount
P: Principal
r: rate of interest
n: number of times per year, hour, day , etc. Interest is compounded
t: time in years
A: Amount
P: Principal
r: rate of interest
n: number of times per year, hour, day , etc. Interest is compounded
t: time in years

Arithmetic and Geometric Sequences - General Forms of a Sequence
Sequence - an ordered list of terms or elements
Arithmetic sequence formula: In an Arithmetic Sequence, the difference between one term and the next is a constant. AKA the Common Difference.
ARITHMETIC FORMULA:
an =a1 +(n-1)d:
n: term number
a(n): nth term
a: first term
r: common difference
Geometric Sequence Formula: In a Geometric Sequence, each term is found by multiplying the previous term by a constant. AKA Common Ratio.
GEOMETRIC FORMULA:
an=a1 + r (n - 1):
n: term number
a(n): nth term
a: first term
r: common ratio
Example: 2, 4, 8, 16, 32, 64...
This sequence has a factor of 2 between each number. Each term ( except the first term ) is found by multiplying the previous term by 2.
Finite sequence - Function with domain 1, 2, 3.
Infinite sequence - Function with domain 1, 2, 3, 4....
Series - Sum of a sequence
Explicit formula - Each domain is an answer not based on any values.
Recursive formula - Each domain is an answer based on a previous answer
