Yes, logarithms are in the family of exponentials, but the original point
was should you focus more on optimizing mass ratio because the relationship
between mass ratio and delta-v is exponential vs. Isp and delta-v is
linear? The reason to focus more would be if the function grows faster
than linear. Since it's an inverse exponential it actually grows slower
than linear. So saying it's in the family of exponentials is kind of
irrelevant to the original point.

When I was taught the exponential functions I was taught that the inverse
exponential was a part of that class. That is, logarithmic functions are
correctly generally referred to as "exponential" or--perhaps somewhat more
accurately--as "inverse exponentials".
