One Step Function Tables and Graphs

Each day Toni records the height of a plant for her science lab. Her data are shown in the table below. The plant continues to grow at a constant daily rate. Write an equation to represent h(n), the height of the plant on the n^th day. Find the height of the plant on day 50.

• h(n) = 2.5n + 0.5

• h(50) = 125.5 cm
