The Base e

e

2.178and on infinite number

e is what type of number

an irrational number

What is e used for?

exponential growth or decay

Leonard Euler

Swiss mathematician and physicist

natural base e

An irrational number approximately equal to 2.71828... .

the base e used in a function formula:

g(x)=a(e^x-h)+k

Reference points for e parent function

0,1 and 1,e

To find the x intercept

Substitute y for 0; and solve for x

To find y intercept

Set x as 0 and solve for y

parent function for e

f(x)=e^x

what is e used as in an exponential function?

The base

Horizontal Asymptote for f(x)=e^x

y=0

Modeling with base e function formula:

g(x)=a(e^c)^x

Find the rate through

1=+/- r=e^c, then solve for r

e^c

the decay factor or growth factor

reference points for base of e function

(h,a+k) and (1+h,ae+k)

c

constant

You can write g(x) as e(^c)^x

by using the power of a Property of Exponents
