Finding Zeros of First and Second-Degree Polynomial Functions

This lesson covers finding zeros of first and second-degree polynomials, focusing on how to determine the x-values that make the function equal zero. It explains the properties of quadratic functions, including parabolas and their vertices, and discusses linear functions and their intercepts. The lesson also covers factoring quadratic equations to find zeros and clarifies the difference between setting a function to zero and substituting zero for x.

What is the graphical representation of a second-degree polynomial function?

• A circle

• A parabola

• A hyperbola

• A straight line

How many zeros can a quadratic function have?

• None

• Exactly two

• One, two, or none

• Only one

What is the process of changing a polynomial from a series of additions or subtractions to a product of two factors called?

• Simplifying

• Expanding

• Factoring

• Differentiating

What is the difference between setting a function equal to zero and finding the function's value when x is zero?

• Setting the function equal to zero finds x-intercepts, while finding the value when x is zero gives the y-intercept

• They are the same process

• Both find the x-intercept

• Both find the y-intercept

What does f(x) stand for in a function?

• The slope of the function

• The function of x

• The y-intercept

• The x-intercept
