Question

Can you help me with this question?

Answer 1

I'm pretty sure the second option is the correct one!

Answer 2

Can you explain?

Answer 3

for x=2 the fuction is pointy so you can't have a derivative there. so only option 2 and 4 remain. the curvature of the plot shows that the second derivative will be negative so the correct answer is D (not B i told you before by mistake)!

Answer 4

hmm how you see whether second derivative is negative by looking at the curvature?

Answer 5

If it is concave then the second derivative is negative. If it's cnvex then the second derivative is positive.

Answer 6

Thanks alot:))

Answer 7

No problem!
