  • F-C4 NAME: Consider !(#) = −2#( + 18# − 28

    1. Is !(#) continuous on the interval [5,9]? Explain.

    2. Explain why there must be a value c in [5,9] such that !(,) = 8

    3. Find the value or values of c in [5,9] such that !(,) = 8 guaranteed to exist in problem 2. D-C1

    4. Use the limit definition of derivative to show that if !(#) = 2#( − 3# + 5, then !/(#) = 4# − 3.

  • D-C7 For each problem, find the derivative function.

    5. 1 = −3#2 − 9#4 + 5(4 #6 + 2

    6. !(#) = 4#( − 6√89: + 5√#(;

    7. 1 = (8 + √# −5(8<
