Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

Well I am kind of stumped on this question and was hopeing for somr guidance.

X 1.1 1.2 1.3 1.4

f(x) 4.18 4.38 4.56 4.73

F is obviously a function and f ''(x)<o for all x in the closed interval. The question asks which of the following has to be for f '(1.2)?

1) f '(1.2)<0 This cant be it becuase f(x) is positive

2) 0<f '(1.2)<1.6

3) 1.6<f '(1.2) <1.8

4) 1.8< f '(1.2) <2.0

5) f '(1.2)> 2.0 This one is saying that the slope at 1.2 is greater than 2, but i suppose the only way to be certain is to graph the points and find out.

As for the rest I'm not entirely sure but hope you guys can assist me ; ;
