Power-rule differentiation

Answers and reasoning. Review before teaching.

  1. 1. For f(x) = 9x^3, find f′(7).

    1323

    The power rule gives f′(x) = 27x^2. At x = 7, f′(7) = 1323.

  2. 2. For f(x) = 9x^3, find f′(5).

    675

    The power rule gives f′(x) = 27x^2. At x = 5, f′(5) = 675.

  3. 3. For f(x) = 5x^2, find f′(6).

    60

    The power rule gives f′(x) = 10x^1. At x = 6, f′(6) = 60.

  4. 4. For f(x) = 6x^5, find f′(4).

    7680

    The power rule gives f′(x) = 30x^4. At x = 4, f′(4) = 7680.

  5. 5. For f(x) = 2x^5, find f′(8).

    40960

    The power rule gives f′(x) = 10x^4. At x = 8, f′(8) = 40960.

  6. 6. For f(x) = 3x^6, find f′(4).

    18432

    The power rule gives f′(x) = 18x^5. At x = 4, f′(4) = 18432.

  7. 7. For f(x) = 8x^5, find f′(3).

    3240

    The power rule gives f′(x) = 40x^4. At x = 3, f′(3) = 3240.

  8. 8. For f(x) = 2x^4, find f′(7).

    2744

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

  9. 9. For f(x) = 1x^3, find f′(4).

    48

    The power rule gives f′(x) = 3x^2. At x = 4, f′(4) = 48.

  10. 10. For f(x) = 12x^6, find f′(5).

    225000

    The power rule gives f′(x) = 72x^5. At x = 5, f′(5) = 225000.

  11. 11. For f(x) = 6x^2, find f′(4).

    48

    The power rule gives f′(x) = 12x^1. At x = 4, f′(4) = 48.

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

    2048

    The power rule gives f′(x) = 32x^3. At x = 4, f′(4) = 2048.
