The blue curve is a power law, not exponential (or geometric) growth. You are correct, the green curve is exponential growth, "Geometric growth" is the special case where the domain is the integers (or some constant multiple of the integers). This is because the values the functions take form a geometric series (in the example it would be 2... f(i+1)/f(i)=2).
