Evaluate each of the following. Show all your calculations.


f′ (3/4)if f(x) = −3x^3 − 7x^2 + 4x − 11

  • calculus -

    again, what is so difficult here?

    f ' (x) = -9x^2 - 14x + 4
    f ' (3/4) = -9(9/16) - 14(3/4) + 4
    = -185/16

    after finding a common denominator of 16 and combining the fractions
