Power-rule differentiation

Answers and reasoning. Review before teaching.

  1. 1. For f(x) = 6x^4, find f′(2).

    192

    The power rule gives f′(x) = 24x^3. At x = 2, f′(2) = 192.

  2. 2. For f(x) = 8x^2, find f′(5).

    80

    The power rule gives f′(x) = 16x^1. At x = 5, f′(5) = 80.

  3. 3. For f(x) = 8x^4, find f′(5).

    4000

    The power rule gives f′(x) = 32x^3. At x = 5, f′(5) = 4000.

  4. 4. For f(x) = 11x^3, find f′(7).

    1617

    The power rule gives f′(x) = 33x^2. At x = 7, f′(7) = 1617.

  5. 5. For f(x) = 7x^2, find f′(4).

    56

    The power rule gives f′(x) = 14x^1. At x = 4, f′(4) = 56.

  6. 6. For f(x) = 7x^5, find f′(9).

    229635

    The power rule gives f′(x) = 35x^4. At x = 9, f′(9) = 229635.

  7. 7. For f(x) = 8x^5, find f′(8).

    163840

    The power rule gives f′(x) = 40x^4. At x = 8, f′(8) = 163840.

  8. 8. For f(x) = 11x^4, find f′(6).

    9504

    The power rule gives f′(x) = 44x^3. At x = 6, f′(6) = 9504.

  9. 9. For f(x) = 8x^3, find f′(6).

    864

    The power rule gives f′(x) = 24x^2. At x = 6, f′(6) = 864.

  10. 10. For f(x) = 4x^3, find f′(8).

    768

    The power rule gives f′(x) = 12x^2. At x = 8, f′(8) = 768.

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

    352

    The power rule gives f′(x) = 44x^3. At x = 2, f′(2) = 352.

  12. 12. For f(x) = 11x^5, find f′(4).

    14080
