Graphing Quadratic Functions in Intercept Form
To graph a quadratic function in intercept form : Identify x-intercepts at and Find axis of symmetry: Calculate vertex: Determine y-intercept by evaluating Plot points and draw parabola Key formulas include expressions such as f(x) = a(x - p)(x - q). This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 2: Quadratic Functions.
Key Concepts
To graph a quadratic function in intercept form $f(x) = a(x p)(x q)$: 1. Identify x intercepts at $(p, 0)$ and $(q, 0)$ 2. Find axis of symmetry: $x = \frac{p + q}{2}$ 3. Calculate vertex: $\left(\frac{p + q}{2}, f\left(\frac{p + q}{2}\right)\right)$ 4. Determine y intercept by evaluating $f(0) = a( p)( q) = apq$ 5. Plot points and draw parabola.
