Graphing Quadratic Functions Techniques

This video tutorial teaches how to graph quadratic functions using a graphing calculator. It compares the traditional paper-pencil method with the calculator method, highlighting the efficiency and capability of technology in solving complex problems. The tutorial provides step-by-step instructions on entering equations, adjusting graph settings, and using zoom and trace functions to analyze graphs. It emphasizes the importance of understanding both methods for a comprehensive grasp of quadratic functions.

What are the two basic methods for graphing quadratic functions mentioned in the lesson?

• Graphing calculator and computer software

• Paper and pencil and graphing calculator

• Graphing calculator and smartphone app

• Paper and pencil and smartphone app

What is the first step in graphing a quadratic equation using a graphing calculator?

• Press the y equals button

• Press the graph key

• Press the zoom key

• Press the trace key

Which button is used to input exponents on a graphing calculator?

• The graph key

• The caret button

• The y equals button

• The x key

What does the x-min and y-min setting control on a graphing calculator?
