If the second derivative is positive at a point, the graph is bending upwards at that point. Similarly, if the second derivative is negative, the graph is concave down. This is of particular interest at a critical point where the tangent line is flat and concavity tells us if we have a relative minimum or maximum. 🔗.Learn calculus with Microsoft Math Solver, a free online tool that can help you with derivatives, integrals, limits, and more.The interval of increasing is #(0,1/2)# and the interval of decreasing is #(1/2,+oo)# The maximum is at the point #(0.5, 0.429)# Calculate the second derivativeStep 1: Finding the second derivative.
