WebA straight line f ( x) = m x + b satisfies the definitions of both concave up and concave because we always have f ( t a + ( 1 − t) b) = t f ( a) + ( 1 − t) f ( b) . Example: y = − 2 x + 1 is a straight line. It is both concave up and concave down. The second derivative is always zero: y ′ = − 2 y ″ = 0 WebAnyway here is how to find concavity without calculus. Step 1: Given f (x), find f (a), f (b), f (c), for x= a, b and c, where a < c < b Where a and b are the points of interest. C is just any convenient point in between them. Step 2: Find the equation of the line that connects the points found for a and b.
WebApr 24, 2024 · If x > 0, then f ″ (x) > 0 so f is concave up. At x = 0 the concavity changes so the point (0, f(0)) = (0, 0) is an inflection point of f(x) = x3. If g(x) = x4, then g ′ (x) = 4x3 …
