The lowest value of the range of the function shown in the graph is -2.
<h3>What is range of a function?</h3>
The range of a function is the set of its possible output values.
In other words, the range of a function is the complete set of all possible resulting values of the dependent variable (y), after we have substituted the domain or independent variables.
The range value are the y values of the graph shown.
Therefore, the lowest value of the range of the function shown on the graph is -2.

after 4 weeks:
.3*4= 1.2 saved
then it is doubled
1.2*2 = 2.40
8 weeks
he will have saved for 4 more weeks ( week 5 6 7 8)
4 * .3 = 1.2 saved
2.4 + 1.2 = 3.6 saved
then it is doubled
3.6 * 2 =7.20
he will have saved for 4 more weeks ( week 9, 10, 11, 12)
4 * .3 = 1.2 saved
7.2+ 1.20=8.40
then it is doubled
8.4*2 = 16.8
He will have 16.80 after 12 weeks
