Power-rule differentiation

Answers and reasoning. Review before teaching.

  1. 1. For f(x) = 2x^4, find f′(7).

    2744

    The power rule gives f′(x) = 8x^3. At x = 7, f′(7) = 2744.

  2. 2. For f(x) = 1x^4, find f′(8).

    2048

    The power rule gives f′(x) = 4x^3. At x = 8, f′(8) = 2048.

  3. 3. For f(x) = 4x^2, find f′(2).

    16

    The power rule gives f′(x) = 8x^1. At x = 2, f′(2) = 16.

  4. 4. For f(x) = 1x^2, find f′(9).

    18

    The power rule gives f′(x) = 2x^1. At x = 9, f′(9) = 18.

  5. 5. For f(x) = 6x^2, find f′(7).

    84

    The power rule gives f′(x) = 12x^1. At x = 7, f′(7) = 84.

  6. 6. For f(x) = 12x^2, find f′(4).

    96

    The power rule gives f′(x) = 24x^1. At x = 4, f′(4) = 96.

  7. 7. For f(x) = 11x^6, find f′(1).

    66

    The power rule gives f′(x) = 66x^5. At x = 1, f′(1) = 66.

  8. 8. For f(x) = 4x^5, find f′(5).

    12500

    The power rule gives f′(x) = 20x^4. At x = 5, f′(5) = 12500.

  9. 9. For f(x) = 11x^3, find f′(2).

    132

    The power rule gives f′(x) = 33x^2. At x = 2, f′(2) = 132.

  10. 10. For f(x) = 3x^2, find f′(7).

    42

    The power rule gives f′(x) = 6x^1. At x = 7, f′(7) = 42.

  11. 11. For f(x) = 12x^4, find f′(8).

    24576
