Exponential function (context/data modeling)

f(x) = a(b)^x + k

Vertical translate

F(x) + k

Horizontal translation

F(x-h)

Vertical stretch or compression

af(x)

Horizontal stretch/compression

f(1/b x)

Y Reflection

f(-x)

X reflection

-f(x)

Kth root

b^ (1/k) = k square root b

Percent increase expression

Y = p(1+r) ^t

Y = final

P = initial

(1 + r) = growth factor

R = percent of increase

T = time in years
