How to write decreasing intervals

WebOnce you have located the vertex of the parabola, you can use interval notation to describe the values over which your parabola is either increasing or decreasing. Write the equation of your parabola in the form y=ax^2 + bx + c, where a, b and c equal the coefficients of your equation. For example, y=5 + 3x^2 + 12x - 9x^2 would be rewritten as ...
