y = k*(e^-x)

---------------

so k = y/(e^-x)

differentiating we get:

1 = -k(e^-x)*(dx/dy)

1/(dx/dy) = -k(e^-x)

dy/dx = -k(e^-x)...substituting for k:

dy/dx = -(y/(e^-x))*(e^-x)

dy/dx = -y

Integral(1/=y)dy = Integral dx

-ln(y) = x + C

x = -ln(y) + C

Is this correct? Thanks.

Yes, correct.

Yes, correct.

Thanks for checking!!!
