Interval Notation
when using interval notation:
-If there is a closed circle you use the bracket
-If there is an open circle you use a parenthesis
-If there is infinity you always use a parenthesis
-If there is a closed circle you use the bracket
-If there is an open circle you use a parenthesis
-If there is infinity you always use a parenthesis
Set builder Notation
when using set builder notation:
-squiggly at the begining and end {,}
- will always have such that xl
-also will always have is an element of x.e.N
For Example: {...2,3,4,5,6,7...}- set builder notation
{xl2<x<7,xeN}
-squiggly at the begining and end {,}
- will always have such that xl
-also will always have is an element of x.e.N
For Example: {...2,3,4,5,6,7...}- set builder notation
{xl2<x<7,xeN}
Domain
To find the domain set equal to zero
or set greater than or equal to zero.
or set greater than or equal to zero.
Application
TIPPING -A restaurant patron has
decided to leave a 15% tip for meals
costing up to $40, an 18% tip for meals
costing at least $40 but less than $100,
and a 20% tip for meals costing $100 or
more. Write a piecewise function to
describe the total amount t the patron
will pay in terms of the meal cost c.
