Graphing Exponential Equations
Graphing Exponential Growth/Decay
0<a<1 = compression
a< 0(negative) = flipped over x-axis.
1. Create the Parent Graph.
2. Identify A,H,K.
3. Create your new T-Chart.
- Domain: All real #'s.
- Range: y>k; when a is positive. y<k; when a is negative.
- Asymptote: y=k.
4. Draw Asymptote
5. Graph new points.
- Exponential Formula: y=a×bx-h+k
- a = multiplier.
0<a<1 = compression
a< 0(negative) = flipped over x-axis.
0<b<1 = fraction; decay, always decreasing.
B is never negative only the multiplier is.
- h = lf/rt; opposite
- k = up/dn
Compound Interest Formula
Compound Interest: Interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan.
A = amount of money accumulated after n years, including interest.
P = principal amount (the initial amount you borrow or deposit)
r = annual rate of interest (as a decimal)
t = number of years the amount is deposited or borrowed for.
n = number of times the interest is compounded per year

Arithmetic and Geometric Sequences
A Sequence is a set of numbers that are in order.
- In an Arithmetic Sequence the difference between one term and the next is you just add the same value each time.
an = a1 +(n - 1)
General Form of an Geometric Sequence
an = a1·rn-1 d
d = the common difference
a1 = the first number in the sequence
n = the number of the place of the sequence you're trying to figure out
n = the number of the place of the sequence you're trying to figure out
