(1 point) This problem has multiple parts which are revealed sequentially after the preceding part has been answered correctly Let f(x) x-cos x on the interval [0, 2Ï]. Fill in the blanks below 1. The curve y f(x) has a y-intercept (is on the y-axis) at y 2. The curve y f(x)has vertical asymptotes at r 3. f is increasing for 4. f is decreasing for r E 5. The local maxima of f occur at 6. The local minima of f occur at r 7. The absolute maximum of f occurs at x - B. The absolute minimum of f occurs at x = 9. f is concave upward for r E 10. f is concave downward for r 11. The point(s) of inflection of f occur(s) at r - Get help entering answers ì§ See a similar example (PDF) Notes: (a) In parts 3, 4, 9 and 10, your answer should either be a single interval, such as (0,1), a union of (non-overlapping) intervals, such as (-inf, 2) U (3,4), or the word NONE. (b) If, for example, f is increasing on (-inf, 2) and f is increasing on (3,4), then please leave your answer as (-inf,2) U (3,4) even if values of f may be lower in the second interval than in the first interval. (Mathematically the union is incorrect in this situation, but it is all that webwork understands.) (c) In 3 and 4 the individual intervals should be the largest possible such intervals. (d) In other parts, your answer should be either a single value, a comma-separated list of values, or the word NONE.
