The equation h = 7m + 8 models the growth of a plant after it was put into a flowerbed. If

m is the number of months since it was planted and h is the plant's height in

centimeters, which statement is valid?

The vertical axis on a graph would

represent the number of months the plant

has been in the flowerbed.

The height of the plant is the dependent

variable.

The domain of the function represents the

height of the plant.

The variable m could be represented as

f (h).

Step-by-step explanation:

the vertical axis would be h, the plant's height, and the horizontal axis would be m, the number of months. This would make statement 2 the only valid statement.

statement 1: Incorrect, as the vertical axis is the height

statement 2: correct, as h depends on m

statement 3: incorrect, as the domain is the horizontal and represents the number of months

statement 4: incorrect, as h = f (m)
