An experiment compares the heights of two plants over time. A plant was 2 cm tall at the beginning of the experiment and grew 0.5 centimeters each day. The function () = 0.5 + 2 represents the height of the plant
in centimeters after t days.
The graph shows the height of the second plant, () in centimeters, as a function of time t in days.

Vertex: ( _ , _ )
Convert to the quadratic function () = 2 − 8 + 5 by completing the
square to vertex form and identify the vertex. Then graph the function.
