Answer:
B. 1 and D. 3.
Step-by-step explanation:
The figure below shows the graphs of f(x) = 3x - 1 (red) and g(x) = 2^x (blue).
The solutions of 3x - 1 = 2^x are the points at which the two curves intersect.
The solutions are at x = 1 and x = 3.
Check:
3 × 1 - 1 = 2¹ 3 × 3 -1 = 2³
3 - 1 = 2 9 - 1 = 8
2 = 2 8 = 8
To fill the table we need to notice that Ali drives 5000 miles per year, then for the distance after a number of years we multiply the mileage for the number of year, then we have that the table will be:
2-10,000
5-25,000
8-40,000
The graph of the points is shown below:
