Answer:
The vertex in this graph is the highest point. when the parabola opens upwards the vertex is the lowest point.
the coordinates in this one are (-2, 9)
the x-intercept is where the line hits the x-axis. since this is a parabola, there are two places.
the coordinates are (-8,0), (4,0) or just -8, 4
the y-intercept is where the line hits the y-axis.
the coordinates for this one are (0,8) or just 8.
