+69 1) f(x)>0, f'(x)<0, and f''(x)>0 for all values of x. If RRAM is used to approximate ∫f(x)dx from x= 0 to 4, is it an over estimate, under estimate, or is it impossible to tell with the given information. Justify your answer.
2) If if a trapezoidal rule was used for the approximation as described in problem 1, would the resulting approximation be an over estimate, under estimate, or is it impossible to tell with the given information. Justify your answer.
