X Intercept Vertex Form. If a is negative, then the parabola opens down. If a is positive, the parabola opens up.
3 Ways to Find the X Intercept wikiHow
Web the intercept form of a quadratic equation is y = a ( x − p) ( x − q), where a is the same value as in standard form, and p and q are the x − intercepts. Look at the coefficient of the x^2 term. If a is negative, then the parabola opens down. The sign of a determines. This form looks very similar to a factored quadratic equation. Below the chart, you can find the detailed descriptions: • how to find roots or. If a is positive, the parabola opens up.
