The equation for the graph sketched below is 
The given graph is an exponential graph and the standard exponential graph is expressed as 
a is the y-intercept of the graph
(x, y) is any point on the graph.
Given the following from the graph;
a = -3
(x, y) = (1, 1)
Substitute the point and the y-intercept into the formula to have

Get the required exponential equation:
Recall that 

Hence the equation for the graph sketched below is

Answer: 
Step-by-step explanation:
Let be "x" the amount of gasoline in liters that the car's tank had at the beginning of the trip.
1. In the first part of the trip the amount of gasoline the car used can be expressed as:

2. After the first part of the trip, the remaining was:
3. In the second part of the trip the car used
of the remaining. This is:

4. The total amount ot gasoline used in this trip was 20 liters.
5. Then, with this information, you can write the following equation:

6. Finally, you must solve for "x" in order to find its value. This is:
