If a student recorded the height of a plant over three months, what is the general formula to represent the height of the plant?

The formula representing the height of a plant as a function of time is typically expressed in the form of a linear equation, where ( h ) is the height of the plant and ( m ) represents the number of months. In general, the formula can be understood as:

[ h = km + b ]

Here, ( k ) signifies the rate of growth per month, and ( b ) represents the initial height of the plant at month zero.

The first choice, ( h = 2m + 7 ), suggests that the plant grows by 2 units per month, starting from an initial height of 7 units. This is a valid representation of a linear growth pattern if these specific values were obtained or observed from the student's data.

To determine which formula accurately reflects the real growth of the plant, one needs to analyze the specific data recorded by the student. If it turns out that the plant indeed increases by 2 units each month and started at a height of 7 units, then this formula correctly captures that growth.

The growth rates and initial heights in the other options may not align with the measured observations. Thus, without additional data indicating otherwise, the first response stands as a reasonable representation of linear
