Question
If $x=c$ is a critical number of the function $f,$ then it is also a critical number of the function $g(x)=f(x-k),$ where $k$ is a constant.
Step 1
A critical number of a function is a number $x=c$ in the domain of the function where either the derivative $f'(c)$ is zero or the derivative does not exist. Show more…

If f(x)= x^2 + (k/x) find k so that f has a critical number at x=3
Suppose $f$ is a differentiable function that possesses a single critical number $c$. If $k \neq 0,$ find the critical numbers of: (a) $k+f(x)$ (b) $k f(x)$ (c) $f(x+k)$ (d) $f(k x)$
