In exponential growth functions, the base of the exponent must be greater than 1. How would the function change if the base of the exponent were 1? How would the function change if the base of the exponent were between 0 and 1?
If the base of the exponent were 1, the function would remain constant and the graph would be a horizontal line. If the base of the exponent were less than 1 but greater than 0, the function would be decreasing (exponential decay). For the function to represent exponential growth, the base must be greater than 1.
