What is the vertex of the graph?

The point (x, y) → (-5, 0) is the vertex of the graph.

Step-by-step explanation:

As the given graph represents Parabola

As we know that Parabolas always contain the lowest point, or the highest point if any given parabola is upside-down. This lowest or highest point is the location where the parabola tends to change its direction and called the 'vertex'.

Hence, from the given graph, we can easily determine that the parabola changes its direction at x = -5, and y = 0.

Therefore, the point (x, y) → (-5, 0) is the vertex of the graph.

Good job man, keep it up!
