Hello!

This is a question about the functionf(x) = 1 + e–2x.

First I have to findf¢(x). I have found this to be: -2e^-2x

Then I have to:

Let P be the point on the graph offwherex= –1/2.

(b) Find an expression in terms of e for

(i) the y-coordinate of P;

(ii) the gradient of the tangent to the curve at P.

and finally I have to

(c) Find the equation of the tangent to the curve at P, giving the answer in the formy=ax+b.

I would appreciate your help.

Thanks,

Amine
