Discuss the below:
Q: Sketch a graph of an equation f(x) = (x)/(x^2) + 4) using (meaning work out each and show me your work to getting the answers) intercepts, extrema, asymptotes, symmetry, and also tell if it's concave up or down and the inflection points. Please do the first and second differentiation and tell me how you did it plus show me the graph. Thrown for a loop about the critical values. 2 and -2 are not critical values, right? If so, are there any?
