Question

find k if f(x)=e^(x^2-k/x) has a relative min/max at x=2 HELP NEED TO CHECK MY ANSWER FAST THANK YOU

Answer 1

What's the derivative of f(x)?

Answer 2

And your exponent could look like this:
\[\large f(x)=e^{x^{2}-\frac{k}{x}}\]
or
\[\large f(x)=e^{\frac{x^2 -k}{x}}\]
Which one is the correct one so I know which equation to deal with.
