Total = Principal × ( 1 + Rate ) ^ years
(Solved by taking logarithms)
Years = log (total / principal) / (log (1 + rate))
Years = log (684 / 600) / (log 1.07)
Years = log (1.14) / (log (1.07)
Years = 0.0569048513364726 / 0.0293837776852097
Years = 1.9366077414
For this case we have a function of the form:
Where,
m: slope of the line
b: cutting point with the y axis.
The line cuts to the y-axis at the point:
Therefore, the value of b is given by:
We now look for the slope of the line.
For this, we use the following equation:
Substituting values we have:
Rewriting:
Then, the equation of the line is:
Answer:
the rule that matches the function shown in the graph is:
