Common and Natural Logarithms
1. For the exponential function ex and logarithmic function log x, graphically show the effect if x is doubled.
The exponential function f (x) = e^x
you will also need to graph f (x) = e^(2x).
The common logarithmic function f (x) = log x
You will also need to graph f (x) = log (2x).
This discusses how to show the effect of doubling on logarithmic and exponential functions.
