1
ƒ(m)
independent variable
independent variable is the INPUT "m"
2
ƒ(m)
dependent variable
dependent variable is the OUTPUT "ƒ"
3
decision-factor equation
mathematical model to help in making a decision, lower is better
eg between two cars:
One could model it as
decision factor = mileage + price + color
4
average rate of change
Divide the difference of the two outputs by the difference of the two inputs
(ƒ(b) - ƒ(a)) / (b-a)
5
decision-factor equation: is lower or higher preferred?
lower

[4,5] is...
interval notation
[3,8) is... the numbers from 3 to 8, including 3 and excluding 8
(-1,1) is... the numbers from -1 to 1, excluding -1 and 1
[4,5] is... the numbers from 4 to 5, including 4 and 5
7
ƒ(m)
domain
ƒ(m)
domaIN is the INPUT variable "m"
8
ƒ(m)
range
ƒ(m)
range is the OUTPUT "ƒ"
