Y Intercept In Vertex Form. Extract a from the first two terms: Y = a[x² + (b/a)x] + c.
Y Intercept Vertex Form Equation Tessshebaylo
If a is negative, then the parabola opens down. Y = a[x² + (b/a)x] + c. Extract a from the first two terms: If a is positive, the parabola opens up. Add and subtract (b/(2a))² inside the bracket: Y = a (x + r1) (x + r2) where a is a known constant, r 1 and r 2. Y = a (x + b)2 + c where a, b and c are known constants and x and y are variables. Factored form looks like this: Y=ax^2+bx+c look at the coefficient of the x^2 term. Web vertex form looks like this:
