Question

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

Answer 1

Is there more to this question?

Answer 2

y= 2e^-x so than

y= 2/(e^x)

and there is again y= e^x

y= 2/(e^x)
y=e^x

so i think there is a system what you need to solve it for x

yes ?

so then you can writing

e^x = 2/(e^x)

e^(2x) = 2 can you solve this for x ?

hope this wan being your exercise ...???
