Please complete the whole question. This is grade 12 Calculus and Vectors and from the chapters of derivative and curve sketch.

8. A) Does f(x) = X have any inflection points? Fully Justify your answer. State any x2 - 4 inflection points that exist. Remember...the second derivative being 0 at a point doesn't necessarily mean that the point is an inflection point; you must show that the concavity changes. (7 marks) B) For what values of x is f (x) concave UP? (1 mark)
