Let me restate what the graph conveys and then walk through how to read the extrema.

- The horizontal axis represents Years ago, ranging from 0 to 120,000 in steps of 30,000, and the vertical axis shows degrees Fahrenheit from 10 to 70 in steps of 10. 
- The curve is described as repeating within one period, with a maximum at (99,000, 60), a minimum at (84,000, 20), and then another maximum at (69,000, 60).

Now, consider how to determine the highest and lowest temperatures from the curve:

- Identify the highest points on the vertical scale that the curve attains. Looking at the coordinates given for the peaks, the curve reaches up to 60°F at the maximum points. There are two such peak locations provided, at (99,000, 60) and at (69,000, 60), indicating that 60°F is the highest temperature reached during this period. 
- Identify the lowest points on the vertical scale that the curve attains. The curve dips down to 20°F at its minimum, specifically at (84,000, 20). This shows that 20°F is the lowest temperature recorded in this cycle.

To confirm there isn’t a higher value hidden elsewhere on the drawn portion, note that the vertical axis labels only go up to 70°F and the described maxima are explicitly at 60°F, not above. Likewise, the minimum value on the curve within this period is explicitly stated as 20°F, with no lower points described in the supplied data.

If you were to read these off the graph directly, you would look for the highest y-values the curve attains (the peaks at 60) and the lowest y-values (the trough at 20) and reference the corresponding year coordinates to understand when these extrema occur.

In sum, the extrema extracted from the described points are: the highest temperature at 60°F (at the two peak locations) and the lowest temperature at 20°F (at the trough).
