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

Which two representations are functions?

• A

• B

• C

• D

What is the equation that represents this relationship?

• y = 1/12x

• y = 12x

• y = 0.6x

• This is not a proportional relationship.

Write the equation for the table.

• y = x + 4

• y = 5x

• y = 4x + 1

• y = x + 5

Identify the constant of proportionality. Write your answer as y=kx

• y=14x

• y=7x

• y=2x

• y=6x
