The key features of a parabola are its vertex, axis of symmetry, focus, directrix, and latus rectum (Figure 8.4.5 ). WebWhen a parabola opens up or down, its equation in the standard form is of the form y = ax 2 + bx + c. Here are the steps to find the vertex (h, k) of such parabolas. The steps are …

Web24 de nov. de 2014 · 1. Direction of the parabola can be determined by the value of a. If a is positive, then the parabola faces up (making a u shaped). If a is negative, then the … Webon the directrix is the difference of the y -values: d = y + p. The distance from the focus (0, p) to the point (x, y) is also equal to d and can be expressed using the distance formula. d = … WebBecause a> 0 a > 0, the parabola opens upward. The axis of symmetry is x= − 4 2(1) = −2 x = − 4 2 ( 1) = − 2. This also makes sense because we can see from the graph that the vertical line x = −2 x = − 2 divides the graph in half.
