Q15. Let f(x) = x² - 18x². (a) Find the domain of f, and, find x-intercepts and y-intercepts of the graph of f. (b) Find the critical values of f. Determine intervals on which the function f is increasing and intervals on which the function is decreasing. Determine relative extrema (maximum and minimum) of ƒ, if any. (c) Determine intervals on which the function f is concave up and intervals on which the function is concave down. Find the inflection points, if any. (d) Sketch the graph of f including intercepts, relative extrema and inflection points.
