1. What are the coordinates of the vertex of the graph? Is it a maximum or minimum?

Coordinates of the vertex: (0, 1), and it is a maximum.

this corresponds to the second of the listed answer options.

Step-by-step explanation:

Notice that the vertex of the parabola is at the very top of the curve, and corresponds to the maximum value that the coordinate "y" can reach for the parabola (y = 1)

The position of that vertex is exactly at the point where x = 0 and y = 1, so this can be written as:

(0, 1)

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
