Technically, no, it isn't. Exponential means that it is of the form k^x, where k is some constant. Quadratic is a special case of polynomial, which is of the form k0 + k1*x + k2*x^2+k3*x^3+...+kn*x^n (where k0, k1, k2... are constants). Exponentials grow much faster than polynomials (in the limit as x --> inf), which is why I said quadratic drag is quite a bit better than if it were to increase exponentially.

(and as I said before, I know I'm being pedantic, but I can't help it on technical topics, since I'm an engineer...)
