The model for each lawn is shown in the table below.
Lawn Fertilizer
Model
A (Control Group)
f(0) = 7x + 6
B (Original Formula)
f(3) = 1.522 +5.50 +11
C (Improved Formula)
f(2)=9.24
Choose ONE equation model to estimate the height of the lawn after 10 weeks. Is this a good model? Explain why or
why not
