The questions are in the photos below: I would like them all solved correctly.

' 13 Question Letf(x) = x3 _ 3x2 9x + 25. Not yet answered Use the derivativef'(x) = 3 x2 6x 9 to determine the following values forf on the interval [4, 2]. Marked out of 1.00 The absolute maximum occurs at x = l7 Flag The value of the absolute maximum is The absolute minimum occurs at x = [:1 The value of the absolute minimum is Question 12 Identify the statement that is FALSE: Not yet answered Olf a function f is continuous on (a, b), then f always has an absolute minimum on (a, b). Marked out of O if a function f is continuous on [a, b], then f always has an absolute minimum on [a, b]. 1.00 Flag O If a function f is continuous on [a, b] and f has no relative extrema in (a, b), then the absolute maximum of f on [a, b] question exists and occurs at either x = a or x = b. O If a function f has an absolute minimum value on (a, b), then there is a critical point of f in (a, b).Question 11 , _ , . , , . The temperature, T, in degrees Celsius, of an object put Into a 210 degree oven Is given as a function of time, t, In minutes, Not yet ' answered by' k Markedoutof T=a(1 t)+b. 200 (i) If the object starts at a temperature of 20 degrees Celsius, find the values of a and b. Hint: Consider t = 0 and the limit t' \"69 lim T(t). question t>oo '1 = C] b = C] (ii) If the temperature of the object is initially increasing at 5 degrees Celsius per minute, find the value of k. Question 9 Not yet answered Marked out of 1.00 F Flag question Consider the function: 3x2 f(x) _ 4x3+x Choose the correct statement: Of(x) has a horizontal asymptote at y =3/4. Of(x) has a horizontal asymptote at y = 0. Of(x) has an oblique asymptote
