Question

Find the slope of the normal line to f(x)=...

Answer 1

\[f(x)=\frac{ (e ^{2x}+1)^{2} }{ e ^{x} }\] at x=0

Answer 2

I got m=-1/4

Answer 4

The derivative of the function at x=0 gives the slope of the function at that point. A normal line's slope will be the opposite reciprocal.

Therefore, yes. You are correct.
