As shown in the figure,the equation of curve C is y f(x),and point (3,2)is aninflection point of curve C.Lines l1 and l2 are tangent lines of curve C at points (0,0)and (3,2)respectively,and their intersection point is (2,4).Assume that function f(x)hasthird-order continuous derivatives,and calculate the definite product medium.To calculate(x+x)f"(x)dx.y432C/(x)I0x234
