Lesson 4-Zeros of the Quadratic Functions
B. Lesson No. 4
C. Lesson Title: Zeros of the Quadratic Functions
D. Lesson Outcome:
At the end of the lesson, the student is expected to:
- Determine the zeros of quadratic functions by factoring & quadratic formula.
- Relate the zeros of quadratic function to the roots of quadratic equation
- Determine the nature of the zeros
E. Review of the Previous Lesson:
General Form of Quadratic Functions
F. Lesson Presentation:
The zeros of the quadratic function , y = ax^2 +bx+c are the roots of the quadratic equation,ax^2+bx+c = 0. These are the x-intercepts of the graph which can be solved algebraically by factoring & quadratic formula.The nature of zeros can be determined by discriminant .
