Answer 9

hi

Answer 10

ok it is still b i think

Answer 11

you know that the second derivative is always positive. this tells you that the function is always concave up

Answer 12

4 and 5 both have parts that are concave down. so they are out as well.

Answer 13

yeah i see them now. 3, 4, 5 all have parts that are concave down, but you are told that
\[f''(x)>0\] for all x not equal 0, so your function must be concave up

Answer 14

only 1 and 2 are always concave up, so it has to be the second one for the reason i stated earlier

Answer 15

Thanks I could you help me on a similar problem dealing with finding the relative minimum on a graph

Answer 16

Relative min is where the function changes from decreasing to increasing, or where the derivative changes from negative to positive.

Answer 17

correct
