Which Form Most Quickly Reveals the Yintercept
Web vertex form looks like this: 1.8k views 3 years ago quadratics. Extract a from the first two terms: If a is positive, the parabola opens up. Y = a (x + r1) (x + r2) where a is a known constant, r 1 and r 2. Factored form looks like this: If a is negative, then the parabola opens down. Y = a[x² + (b/a)x] + c. Y = a (x + b)2 + c where a, b and c are known constants and x and y are variables. Add and subtract (b/(2a))² inside the bracket:
Add and subtract (b/(2a))² inside the bracket: Extract a from the first two terms: If a is negative, then the parabola opens down. 1.8k views 3 years ago quadratics.
