2. Let f be a function that is continuous on the interval [0, 4). The function fis twice
differentiable except at x = 2. The function fand its derivatives have the properties indicated in
the table above, where DNE indicates that the derivatives of f do not exist at x = 2.

g(x)= [f(t)dt on the open interval (0,4) For 0<x< 4,
find all values of x at which g has a relative extremum. Determine whether g has a relative
maximum or a relative minimum at each of these values. Justify your answer.
d) For the function g defined in part (c), find all values of x, for 0<x<4, at which the graph
of g has a point of inflection. Justify your answer.
