Answer 1

Answer 2

any function that changes from concave up to concave down at (-1,2) will do. The first derivative must be undefined for a vertical tangent line (0 is horizontal). the second derivative must be undefined also, because it represents the slope of the slope of a function which is going to infinity at -1. The last one is impossible

picture something like
\[f(x)=\sqrt[3]{x+1}+2\]
