Function: Each input must have exactly one output
A correspondence in which each member of the domain is matched with exactly one
member or the range
Domain
Range
23
1
18
23
19
This IS a function
Domain: A set of numbers
Correspondence: Area of a triangle
Range: a set of triangles
Can a member of the domain correspond to more than one member of the range?
YES
Since members of the domain can be paired with more than one member of the range, is
the correspondence a function or not a function?
NOT A FUNCTION
Domain: A set of numbers
Correspondence: Area of a triangle
Range: A set of triangles
NOT A FUNCTION
Domain: Set of packages
Correspondence: Mailing address
Range: Set of zip codes
NOT A FUNCTION

The function H(x)=2.75x+71.48 can be used to predict the height, in centimeters, of a
woman whose humerus (the bone from the elbow to the shoulder is x cm long.
Predict the height of a woman whose humeris is 34cm long.
H(34)= 2.75(34)+71.48
H(34)= 93.5+71.48=164.98
The function p(d)=1+ d/33 gives the pressure in atmospheres (atm), at a depth d in the sea
(d is in feet). Note that p(0)=1atm
P(33)=2, and so on. Find the pressure at 190 feet.
P(190)= 1+ 190/33= 1/1+190/33= 33/33+190/33= 223/33
