Question

A function f satisfies the following conditions.
f(4) = 23
f '(4) = 2
f ''(x) < 0 for x ≥ 4
Which of the following are possible values for f(6)? (Select all that apply.)

Answer 1

so basically, y= 23 or 4 when x = 4

Answer 2

y can also be also less than zero when x is greater than or equal to 4

Answer 3

if x = 6....then it is greater than (or = to) 4

Answer 4

which means you must use f(x) is <0 to solve

Answer 5

Wait......what are your answer choices?

Answer 6

25, 27, 29, or none of these

Answer 7

Y must be less than 0

Answer 8

25 27 or 29 is not less than 0

Answer 9

none
