Finding Zeros and Extreme Values using Factored and Vertex Forms of Quadratic Functions

This video tutorial covers the use of quadratic functions in solving problems, specifically focusing on finding zeros and extreme values using factored and vertex forms. It introduces the concept of quadratic functions, explains how to find zeros by solving and graphing, and discusses the vertex form to find maximum and minimum values. The tutorial applies these concepts to a practical problem involving a rocket launched from a rooftop, demonstrating how to determine the rocket's maximum height and the time it takes to reach the ground.

What are the two forms of quadratic functions used to find zeros and extreme values in this lesson?

• None of the above

• Standard and Factored forms

• Factored and Vertex forms

• Standard and Vertex forms

Which of the following is NOT a form of quadratic function discussed in the lesson?

• Factored form

• Linear form

• Vertex form

• Standard form

What is the vertex of a quadratic function in vertex form?

• The point (p, q)

• The point (h, k)

• The point (a, b)

• The point (x, y)

If the value of 'a' in a quadratic function is less than 0, what does the graph do?

• Forms a straight line

• Opens downwards

• Opens upwards

• Has no vertex

At what time does the rocket reach its maximum height?

• 3 seconds

• 1 second

• 2 seconds

What is the maximum height reached by the rocket?

• 144 feet

• 130 feet

• 150 feet

• 120 feet

How long does it take for the rocket to reach the ground?

• 6 seconds

• 5 seconds

• 4 seconds
