Using exponetial is y1 = 0.05*5+10000 the annual interest rate is 5%. create y2 that has a larger principal but smaller interest rate than y1, and y3 that has a larger interest rate but smaller principal value than y1; make it so all three functions have the SAME loan amount owing in the year 2029, to the nearest $0.10. Explain how you did it. Comment on what would be more realistc than what has been done here, referencing generally how that would affect the math 30-2
