Problem

Interpret the overtaking point of \(L\) and \(E\) in the displayed context graph. State the approximate equality and difference at the crossing, compare the models before and after it, and explain the estimate status for daily observations with the contextual units.

Context graph of L(d) and E(d), measured in dollars over days; L is above E before an unlabeled crossing near day 7, and E is above L after it.

at overtake = L(7)≈E(7); before = L>E before 7; after = E>L after 7; status = overtaking means growth rates, not totals, are equal; units = days and dollars

at overtake = L(7)=E(7)=7 dollars; before = L>E before 7; after = E>L after 7; status = exact because day 7 is labeled; units = days and dollars

at overtake = L(7)≈E(7) dollars and E-L≈0; before = L(d)>E(d) for modeled days before about 7; after = E(d)>L(d) for modeled days after about 7; status = day 7 is an approximate crossing, and daily observations may only bracket exact equality; units = days and dollars

at overtake = L(7)≈E(7); before = E>L before 7; after = L>E after 7; status = approximate; units = days and dollars
