Evaluating Linear Functions and Their Properties

Mr. Buffington explains how to solve functions using tables, graphs, and equations. He introduces function notation and demonstrates solving functions by substituting values into equations. The video covers input-output relationships, graph interpretation, and solving equations using substitution.

What are the three methods discussed for solving functions?

• Tables, charts, and diagrams

• Tables, graphs, and equations

• Diagrams, tables, and graphs

• Graphs, charts, and equations

What does function notation typically involve?

• Writing Z equals something

• Writing f of X equals something

• Writing y equals something

• Writing X equals something

In function notation, what does f(x) represent?

• The product of F and X

• The sum of F and X

• F times X

• The function at the point where X is a specific value

When using a table to solve functions, what is typically given?

• Neither X nor Y values

• Both X and Y values

• Only Y values

• Only X values

In a table, what is the usual position of input and output values?

• Both input and output on the right

• Both input and output on the left

• Input on the left, output on the right

• Input on the right, output on the left

What is the output when X is equal to 1 in the given table example?

• 6

• -9

• -5

• 7

How do you determine the output value from a graph?

• By looking at the x-axis only

• By finding the corresponding y-value for a given x-value

• By looking at the y-axis only

• By finding the corresponding x-value for a given y-value

What is the output when X is equal to 1 on the graph?

• 3

• 1

• 2

• 0

What is the output when X is equal to -2 on the graph?

• 2

• 1

• 0

• 3

What is the process of solving functions using equations?

• Substituting y-values into the function

• Substituting x-values into the function

• Finding the product of x and y values

• Finding the sum of x and y values
