Quadratic Relations II (Chapters 4 & 5)
Quadratic Relations
Lesson 9: Different Forms of Quadratic Relations (5.2 and 5.5)
Video 1: Identifying Quadratic Relations in Various Forms
Standard Form: y = ax² + bx + c where c is the y-intercept
Vertex Form: y = a(x − h)² + k where vertex is (h, k)
Intercept Form: y = a(x − r) (x − s) where x - intercepts are r and s
Standard Form: y = ax² + bx + c where c is the y-intercept
Vertex Form: y = a(x − h)² + k where vertex is (h, k)
Intercept Form: y = a(x − r) (x − s) where x - intercepts are r and s
Video 2: Quadratic Relations in Vertex, Standard and Intercept Form
Video 3: Understanding the Vertex Form of Quadratic Relations
Video 4: Converting Vertex Form to Standard Form (Part 1)
Video 5: Converting Vertex Form to Standard Form (Part 2)
Video 6: Converting Vertex Form to Intercept Form
Video 7: Finding Vertex Given the Standard Form of Quadratic Relations
Video 8: "Zeros" are x - Intercepts of Quadratic Relations
Quadratic Relations can have Two Zeros, One Zero or No Zero
Quadratic Relations can have Two Zeros, One Zero or No Zero
Video 9: Finding Zeros Algebraically by Factoring
Important to note the misconception regarding x - intercepts and its coordinates:
For y = a(x − r) (x − s), x - intercepts are r at (r, 0) and s at (s, 0)!
