The Quadratic Formula PowerPoint
... Finding the Equation of a Quadratic Function • Find the function with zero 4 and a = -3 • Because there is only one zero, and we know that a quadratic function must have two zeros, 4 must be a double zero • x=4 and x=4 • Factors: (x – 4) and (x – 4) • f(x) = -3(x – 4)2 • f(x) = -3(x2 – 8x + 16) • f ...
