The slope of an absolute function at the point where it evaluates to zero is undefined.
Here, when x=1, so |4x-4|=|4-4|=|0|, the slope is undefined. This is where the vertex of the "V" on the graph of the absolute value function.
Solution
- 89 gallons contains 40 gallons twice such that:

- This means that we can find at least 200% of 40 gallons in 89 gallons. This gives us what to expect.
- To get the percentage we are looking for, we should use the formula:

New, in this case, is 89 gallons, Old is 40 gallons.
- Thus, we can calculate the percentage as follows:

Thus, the answer is 222.5%
