(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Eliminate the parameter given

x=2e^t, y=2e^-t

3. The attempt at a solution

lnx = ln2 + t, so t = lnx - ln 2

This gives:

y=2e^(ln2-lnx)

y=2(e^ln2 * e^-lnx)

y= -4x

This does not, however, match the graph of the parametric function on my calculator. Have I made a mistake?
