This is the graph of f. - 2 5- 4- A 3 h(x) Let g(z ) = f(t ) at. 2 What is an appropriate calculus-based justification for the fact that g has an inflection point at z = c? Choose 1 answer: f is concave up at = = c. 6 -5 -4 -3 -2 -1 1 2 3 4 5 6 f has a relative minimum at I = c. f(c) = 0 Approximate the area between h(x) and the x-axis from x = -6 to x = 6 using a trapezoidal sum with 4 equal subdivisions.
