Step-by-step explanation:
The exponential model indicates that hydropower energy generation has increased by 2.3% (0.023).
<h3>What is an exponential function?</h3>
An exponential function can be defined as a type of mathematical equation whose numerals are generated by a constant that's raised to the power of an argument.
Based on an exponential model for this data, we can deduce the following:
- Mathematically, the exponential function for the given data is given by

- The exponential model indicates that hydropower energy generation has increased by 2.3% (0.023).
- Hydropower energy generation in 25 years after 1970 was closest to 2270 TWh.
- Because the correlation coefficient indicates a strong correlation between the model and the data, this prediction can be accepted with confidence interval of 98.7%.
