-4 is the slop of the line
The following statements in this case are correct:
1) The independent variable is t.
2) The dependent variable is f (t).
3) When f (2) = 1,323, the 2 represents "the year 2002," and the 1,323 represents "1,323 tons of garbage produced."
4) When f (4) = 1,458.6, the 4 represents "the year 2004," and the 1,458.6 represents "1,458.6 tons of garbage produced."
Note: for statements 3) and 4) the following is done:
f (2) = (1200) * (1.05) ^ 2 = 1323
f (4) = (1200) * (1.05) ^ 4 = 1458.6
Is this done or do you still need it answered?
