The wording for question 8 is unclear. The sentence "Ifthere exists a point c such thatf(c) = 0" should instead be "Suppose there exists a pointcsuch thatf(c) = 0".

Let f(a:) be continuous over an interval [(1, b]. The mean value theorem for integrals states that there is at least on point e such that a S C S b and b h ab/ mass or / f(w)dx=f(c)
