Since the function is exponential, the obvious thing is using a
logarithmic scale on the vertical axis.  Only reason I see to do what
you ask is for didactic reasons.

You should magnify the negative values of the function by 10 and then
change the vertical labels to be magnified by 10 as well.  This function
may help: https://octave.sourceforge.io/plot/function/tics.html
