### Question:

Which part of a graph is meant by the term “vertex” when used in mathematics?

### Answer:

Step 1

Vertex: (0,-4)

A quadratic’s vertex is the point at which its value is either the greatest or the least. A parabola has opened upwards, hence this point is its extremum.

Step 2

No symmetry exists above or below the equator (X).

The axis of symmetry is the x= function that crosses the vertex of the quadratic at (0, -4).

Step 3

Minimum:(0,-4)

Due to the parabola’s upward widening, the minimum will be reached. The lowest point is at the zenith.

Result

Vertex: (0,-4)

Axis of Symmetry: x=0x=0

Minimum: (0,-4)
