Elle Measured the height of a plant, in inches,Every week for four weeks after planting it.

The height of the plant, h, in inches, Can be modeled by the function h(t) = 1.5t + 3, where t represents the time in weeks.

Answer:

Option B: 21 inches

Step-by-step explanation:

We are given the function h(t) = 1.5t + 3, where t represents the time in weeks.

At t = 0;

h(0): 1.5(0) + 3 = 3inches

At t = 1;

h(1): 1.5(1) + 3 = 4.5 inches

Thus, after 12 weeks, height will be;

h(12): 1.5(12) + 3 = 21 inches

Option B is correct
