9. A farming cooperative collected data on the effect of different amounts of fertilizer, x, in hundreds of kilograms per hectare (kg/ha), on the yield of carrots, y, in tonnes (t).
Fertilizer
0.50 0.75 1.00 1.25 1.50 1.75 2.00 0.25
(hundreds kg/ha) 0.65 0.90 0.95 1.10 1.05 0.90 0.80 0.15 0.45
Write an equation to predict the yield of carrots based on:
1) Fertilizer used.
b) State any restrictions on the domain and range of your model.
How much fertilizer is used for a yield of 0.75 t?
