Question Find the domain and range of a quadratic function with vertex at $(-4,0)$. Determine if the function opens upwards or downwards and if the graph intersects the x-axis.

Studdy Solution
If the quadratic function opens upwards (a >0), the graph will intersect the x-axis at the vertex, because the vertex is the minimum point of the graph.
If the quadratic function opens downwards (a <0), the graph will also intersect the x-axis at the vertex, because the vertex is the maximum point of the graph.
In both cases, the graph of the function intersects the x-axis at the point (-4,0).
