Here’s a table to also give extra info
D (2, 5) > (-6, -2)
E (5, 5) > (-3, -2)
F (6, 3) > (-2, -4)
G (5, 1) > (-3, -6)
H (2, 1) > (-6, -6)
I (1, 3) > (-7, -4)
Looking at the transitions all side by side, you could tell they all turn negative so one can assume the transition is a negative.
Therefore, the rule would be:
(x-8, y-7)
First term is 13m with factors 13 and m
second term is -2n with factors -2 and n
15% each yer
represented by
f(x)=60(1.15^x)
xintercept is when the function equals zero
since it increases only, it cannot equal zero and does not have an x intercept
after 4 years the investment value is 104
after 6 yaers value is 138.7
after 7.86 years the value is179.98 which is roughly 3 times of 60
8 years later183.54 close enough
answers
f(x)=60*1.15^x
after 7.86 years value is 3 times initioal value
after 8 years value is 184
