Hi I need help with this 3 questions:

1.

Consider the function f (9:) = 9:4 98:232 + 9, Find the absolute minimum value of this function. Answer: 3 find the absolute maximum value of this function. Answer: a 65x315. Suppose a farmer has 3600 feet of fence and wishes to create two rectangular pens of the same dimensions with the two pens sharing one side (i.e. since the pens share one side, there is a total of 7 sides of fence). What is the maximum area of each of the pens? O 202, 500 square feet Q 270, 000 square feet 0 12,960,000 49 square feet 0 259, 200 square feet 0 540, 000 square feet Suppose a twice differentiable function f satisfies the conditions: . f' (-3) = f'(3) = 0, . f'(x) > 0if -3 3 orx 0, and f" (x) > 0ifx
