- A tree was planted in the ground.
Its height, \(H\) metres, was measured \(t\) years after planting.
Exactly 3 years after planting, the height of the tree was 2.35 metres.
Exactly 6 years after planting, the height of the tree was 3.28 metres.
Using a linear model,
- find an equation linking \(H\) with \(t\).
The height of the tree was approximately 140 cm when it was planted.
- Explain whether or not this fact supports the use of the linear model in part (a).
