exponential growth function
exponential decay function
linear function with a positive rate of change
linear function with a negative rate of change

linear function with a positive rate of change
explain
A linear function with a positive rate of change would best model this situation because for every square meter of solar paneling added, 0.2 kilowatts of electricity is produced. The relationship between the amount of solar paneling and the amount of electricity produced is constant and increases proportionally. This is characteristic of a linear function with a positive rate of change, where the output (electricity produced) increases at a constant rate relative to the input (amount of solar paneling).
