At the end of week 3, plant 1 is 0.6 inches taller than plant 2.
How much taller is plant 1 than plant 2 at the end of week 3?
For plant 1, the height (in inches) equation as a function of the number of weeks is:
[tex]h_1(w) = 2.5 + \frac{4}{10}*w[/tex]
The height for w = 3 is:
[tex]h_1(3) = 2.5 + \frac{4}{10}*3 = 3.7[/tex]
So the height at the end of week 3 is 3.7 inches.
For plant 2 the equation is:
[tex]h_2(w) = 2.5 + \frac{1}{5}*w[/tex]
The height for w = 3.
[tex]h_2(3) = 2.5 + \frac{1}{5}*3 = 3.1[/tex]
So the height at the end of week 3 is 3.1 inches.
The difference is:
3.7 in - 3.1 in = 0.6 in
At the end of week 3, plant 1 is 0.6 inches taller than plant 2.
