Math 106 Final Exam
Domain - correct answer Inputs, independent variable
x-values
Range - correct answer Output, dependent variable
y-values
Function - correct answer A relationship such that each element in the domain corresponds to exactly
one element in the range
Example of a function:
Is the length of a song in seconds a function of the price of the song? - correct answer No,
Independent: Length
Dependent: Price
Function Notation - correct answer f(x)
"f" is the function name
(x) is the independent variable
Difference Quotient - correct answer f(x+h)-f(x)/h
Natural Domain - correct answer The set of real numbers that output real numbered solutions to the
function
Restrictions on domain - correct answer Even roots: radicand ≥ 0
Rational functions: denominator ≠0
Every other function has a domain of all real numbers
