Exploring Graphing Functions in Algebra

The video tutorial covers graphing functions, starting with an introduction to graphing with limited domains and extending to all real numbers. It explains how to graph functions by finding ordered pairs and discusses the importance of verifying graph accuracy. The tutorial also explores real-world applications, such as predicting sea level rise and estimating distances. The lesson concludes with a quiz to reinforce learning.

What is the approximate rate at which sea level is rising per year?

• 4.5 millimeters

• 2.5 millimeters

• 1.5 millimeters

• 3.5 millimeters

What is the first step in graphing a function given a limited domain?

• Find the range

• Solve for y using given x values

• Draw the graph

• Identify the function type
