I learned how standard form quadratic functions can be interpreted from the equation y=a(x-p)²+q. The “a” is the shape of the graph. “a” value can tell you skinner the parabola becomes. the wider the parabola becomes. If the “a” have “-” that parabola will go down, ì there have “+” it will go up. Big or small parabola depends on how big of the number of “a”.
