Answer:

Step-by-step explanation:

The vector GH has horizontal and vertical components of 5 and 12. You recognize that these are part of the Pythagorean triple (5, 12, 13), so the length of GH will be 13.

_____

In case you haven't run across this fun fact often enough to remember it, you can compute the length from the distance formula:

d = √((x2-x1)² +(y2-y1)²) = √((-1-4)² +(10-(-2))²) = √((-5)² +12²)

d = √(25+144) = √169 = 13

If the axis of symmetry is x=-1, the vertex will have x-coordinate -1.

The point (0, 5) cannot be the vertex. The friend is not correct.

_____

If the point (1, 5) is on the graph so is the image of that point when it is reflected across the axis of symmetry. That image point is (-3, 5). A parabola that goes through points (1, 5) and (-3, 5) will not go through point (0, 5).
