Elle measured the height of a plant, in inches, every week for four weeks after planning it. the table shows her data.
week: height (in inches):
0 3
1 4.4
2 6.2
3 7.3
4 9.1
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.
Based on this model, what is the best prediction for the height of the plant after 12 weeks?
a 16.5 inches
b 21 inches
c 22.5 inches
d 27.3 inches
To find the best prediction for the height of the plant after 12 weeks, substitute t = 12 into the function h(t) = 1.5t + 3:
h(12) = 1.5(12) + 3 = 18 + 3 = 21
Therefore, the best prediction for the height of the plant after 12 weeks is 21 inches.
The answer is b) 21 inches.
