Arithmetic Sequence Formula

a_n=a_k+d(n-k)

Geometric Sequence Formula

g_n=g_k(r)^n-k

Vertical translation up

f(x)+k

Vertical translation down

f(x)-k

Horizontal translation right

f(x-h) ex: 2^x-3

Horizontal translation left

f(x+h) ex: 2^x+6

Vertical stretch / shrink

a(f(x)) stretch: 3(2^x) shrink: 1/2(2^x)

Horizontal stretch / shrink
