Question

Does this graph look right? (graph below)
y=839.06-89.616625^12x
y=89.616625^12x
Since it's a word mortgage problem, I put a restriction on x, 1 to 30 (for 1 to 30 years).

Answer 1

yes it does

Answer 2

Okay; great! Do you know if I should put a restriction on y or not (0 to infinity) if it has to be a positive number, or should I leave it?
