Im sorry i have no work to show for this etc...but i need in the next 10-20 minutes or i fail this test....This depends on whether i pass the class this semester. !!!! Long Story to lazy to type and not much time!

A function H exists where H(4)= -3

H'(x)= x^2 - 2 / x

a)Determine where a horizontal tangent exists on the graph H, and if so locate a maximum/minimums. ( u cant do this with a graph it wont count, must be done algebraicly.)

b)Determine on what interval the graph H performs a concave down.

c) Determine the equation of the line where the tangent is at x = 4 On the original graph.

d)Is the Tangent of the line in C) below or above the curve? Explain.
