For the following function, $\backslash (\backslash$mathbf$\{$a$\}\backslash ))$ give the coordinates of any critical points and classify each point as a relative maximum, a relative minimum, or neither; $\backslash (\backslash$mathbf$\{$b$\}\backslash ))$ identify intervals where the function is increasing or decreasing; c$)$ give the coordinates of any points of inflection; d$)$ identify intervals where the function is concave up or concave down, and e$)$ sketch the graph. $\backslash [$ q$($x$)=\backslash$frac$\{$x$\}\{$x$^\{2\}+4\}\backslash ]$ a$)$ What are the coordinates of the relative extrema? Select the correct choice below and, if necessary, fill in the answer box$($es$)$ to complete your choice.
