Question

Give an example of quadratic paljnomia whose graph is open downward parabole​

Answer 1

Answer:

There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.

The graph of a quadratic equation in two variables (y = ax2 + bx + c ) is called a parabola. ... We say that the first parabola opens upwards (is a U shape) and the second parabola opens downwards (is an upside down U shape). In order to graph a parabola we need to find its intercepts, vertex, and which way it opens
