f(z) = 13 + 13 (a) Determine the domain of f. (b) Determine the e- and y- intercepts. (e) Find the critical numbers of f d) Find the intervals where f is increasing or decreasing, and determine any relative extrema. (e) Find intervals where f is concave upward or concave downward, and determine any inflection points. f) Evaluate lim f(x) and lim f(z) (g) Use the above information to sketch the graph of y = f()
