Let f (m) = \\/m2 +39 forl

Let f (x) V/ -k c forl 7. We wish to estimate 7 1 by the Trapezoidal Rule. a) Divide the domain of f into 4 sub-intervals of equal length. Calculate their common length (exact value). b) Find the approximation of 7 1 that the Trapezoidal Rule produces with 4 sub-intervals. Give the answer with 0.0001 precision. Number
