On which intervals is f concave down

Web21 de nov. de 2012 · Below x = -2, the value of the second derivative, 30x + 60, will be negative so the curve is concave down. For higher values of x , the value of the second derivative, 30x + 60 , will be positive so the curve is concave up. We can conclude that the point (-2,79) is a point of inflection. Consider f(x) = x4. WebSteps for Identifying Where a Graph is Concave Down by Examining the Graph Step 1: Mark intervals on the graph where the graph is curved like part of a frown.
