Khan Academy: Algebra: Domain and Range 2

After defining a simple function from a word problem, this video shows how to find the domain and range of that function. The goal is to reinforce the definitions of domain and range with a concrete example.

After defining a simple function from a word problem, a short video shows how to find its domain and range. The instruction reinforces the definitions of domain and range with a concrete example.

Video determining the domain and range of a relation given as a table of values. [2:43]

Video solving for the domain and range of a specific function defined verbally. Equation for function is found before defining the domain and range. [3:36]

Video determining the domain and range of a quadratic function given as an equation written in function notation. Graph of the function is created by finding specific points to help find the range. [8:07]

Sal introduces the concept of "range" of a function and gives examples for functions and their ranges. [6:38]

Video simplifying an algebraic expression with fractional exponents and a square root. [7:32]

This video demonstrates how to solve word problems related to a person's age by setting up and solving equations based on the information given in the problem. There are two sample word problems. [9:57]

A straightforward explanation of domain and range. The domain of a set of coordinates are the x-values, and then range are the y-values of the set.
