WebWe can see that f ( x) concaves downward for the intervals, ( − 1, 0) and ( 0, 1). Meanwhile, the curve concaves upwards for the intervals, ( − ∞, − 1) and ( 1, ∞) . Moving on to f ( x) ’s points of inflection, let’s go back to the values of x that return f ′ ′ ( x) to zero. WebConcave Down: The graph of a function f(x) f ( x) is concave down when it is curved like a hill or a frown. Functions that are concave down can be either increasing or...
