The vertex is (.640, 6.452) and this means that at .640 seconds the swing was 6.452 inches from the ground. It is also the minimum so it is the lowest point.

The Y-Intercept represents the starting point when the time is 0 seconds the swing is 26.1 inches from the ground. (0,26.1)

Anne has a beautiful swing set and decides to go play on it. She then realizes that this is a quadratic and wants to take some measurements. Assume that the height from the ground varies with the time. When she pulled back the swing to start it was 26.1 inches off the ground. After 0.30 seconds passed, she was 12 inches from the ground and at 1.24 seconds she was 23.7 inches off the ground.
