Question QUESTION: How would I go about finding the exponential function ex and logarithmic function log x, graphically show the effect if x is doubled.
ANSWER: On e^x, note that as x gets extremely negative, e^x gets close to zero from the positive side (above the x axis). At 0, the function is 1. On the positive side, it quickly goes up faster and faster all of the time as x gets greater. The ln(x) function is the inverse of e^x, so draw a line x=y. The function treats this line like a mirror.
When x is doubled, the curve is increased in the x direction by around eight times.
Thank you for letting me answer this question and I am willing to explain it further or ask more questions.

QUESTION: How would I show this graphically?
Answer I have never done this before, but there's a firts time for everything. Let me try and send an image...
didn't work. Maybe I'll figure out to do it eventually.
Anyway, e^x is a graph that starts out right on top of the x axis when x is negative and increases slowly to one when x is 0. After that, it slopes upward faster and faster as it goes to the right.
