# Representing functions as rules and graphs

## By MathPlanetVideos

Write a rule for the function:

# Recognizing functions from graphs

Sal checks whether a given set of points can represent a function. For the set to represent a function, each domain element must have one corresponding range element at most.

# Comparing linear functions

Sal is given a table of values of a linear function and four linear graphs, and is asked to determine which graph has the same rate of change as the function represented in the table.

# Comparing linear functions

Sal is given a table of values of a linear function and four linear graphs, and is asked to determine which graph increases faster than the function represented in the table.

# Constructing linear functions word problems

Sal is given a verbal description of a real-world relationship involving a melting iceberg, and is asked to find the formula of the function that represents this relationship.

# Recognizing functions from tables

Sal checks whether a table of people and their heights can represent a function that assigns a height to a name.

# Find inverse values of functions

Sal is given a line segment on the coordinate plane, and he graphs the inverse of the function represented by that segment.

# Find inverse values of functions

Sal is given a line segment on the coordinate plane, and he graphs the inverse of the function represented by that segment.

# Find inverse values of functions

Sal is given a line segment on the coordinate plane, and he graphs the inverse of the function represented by that segment.

# Comparing features of functions

Given several functions represented in different forms (as a formula, as a graph, and as a table of values), Sal finds the one with that has no x-intercepts.

# Constructing linear functions word problems

Sal is given a verbal description of a real-world relationship involving a melting iceberg, and is asked to find the formula of the function that represents this relationship.
