For that, we need the first derivative. To find the first derivative, we can use the power rule. We lower the exponent on all the variables by one and multiply by the original variable.f′′(0)=0. By the Second Derivative Test we must have a point of inflection due to the transition from concave down to concave up between the key intervals. f′′(1)=20>0. By the Second Derivative Test we have a relative minimum at x=1, or the point (1, -2). Now we can sketch the graph. CC BY-NC-SA. Now, look at a simple rational function.
