SOLUTION: How do I complete this problem? For the exponential function ex and logarithmic function log x, graphically show the effect if x is doubled. How do I calculate and plot these?

Question 149866: How do I complete this problem? For the exponential function ex and logarithmic function log x, graphically show the effect if x is doubled.
How do I calculate and plot these?
1. ex and e2x
2 logx and log2x
Correct reasoning of the effect of doubling the value of x in logarithmic and exponential functions
This is one tough question. Thanks so much.

I think the 1st part is and
Note that

You can check this with simple numbers
and

is this true?

OK
and
The general rule is
Again, you can check this with numbers

this is true
