In each part, find k so that f has a relative extremum at thepoint where x = 3.(a) f(x)

Chapter 4, Problem 77

(choose chapter or problem)

In each part, find \(k\) so that \(f\) has a relative extremum at the point where \(x=3\).

(a) \(f(x)=x^{2}+\frac{k}{x}\)

(b) \(f(x)=\frac{x}{x^{2}+k}\)

k

f

x = 3

f(x) = x^2 + k/x

f(x) = x/x^2 + k
