WebbAnswer (1 of 3): y = -(x - 5)(x + 2) has the desired x-intercepts and opens downward. One can also multiply this by a positive constant. WebbA parabola’s vertex is the maximum value when a < 0, and in this case, the parabola is concave (concave down) and opens downward (like a dome shape). Of course, the vertex of a parabola can like on the x-axis, on the y-axis, and in some cases on both at the same time (that is, the vertex is at the origin). In this article, we’ll answer some ...
WebbA parabola can be upside down (we also say that it opens downward). This happens when the leading coefficient of x 2 if negative (that is, when a < 0). On the other hand, a parabola opens upward if the leading coefficient of x 2 is positive (that is, when a > 0). For example, the graph of y = -x 2 is an “upside down” parabola that opens downwards.
