x%28years%29|g%28x%29=3x
1 |3....g%281%29+=+3%2A1=3
2|6....g%282%29+=+3%2A2=6->values that is missing in the table
3|9....g%283%29+=+3%2A3=9

Jane's savings in dollars
x%28years%29|f%28x%29=3x%2B3
1 |6....f%281%29+=+3%2A1%2B3=6
2|9....f%282%29+=+3%2A2%2B3=6%2B3=9
3|12....f%283%29+=+3%2A3%2B3=9%2B3=12->values that is missing in the table
Mariah's savings in dollars

g%28x%29=3x best describes Jane's savings in the long run
and f%28x%29=3x%2B3 Mariah's savings in the long run
