Question

Use the image to answer the question.

An open, downward facing parabola is graphed on a coordinate plane. The x-axis ranges from negative 2 to 5 in increments of 1. The y-axis ranges from negative 1 to 16 in increments of 2.

Interpret the following quadratic function model and graph given the following context. A volleyball is served into the air at 26 ft./sec from a height of 4.5 ft. The quadratic equation represents the height of the ball over time and in seconds. The graph illustrates this path where x represents the time in seconds and f(x) represents the height in feet. Approximately how long does it take for the volleyball to reach maximum height?
