A few statements from this skill. Answers, hints and worked solutions live in the practice session.

  1. Warm-up

    Let f(x)=2x2+4x+2f(x) = 2x^{2} + 4x + 2. Compute the average rate of change of ff over the interval [−3,3][-3, 3].

  2. Warm-up

    Let f(x)=4x2−5x+1f(x) = 4x^{2} - 5x + 1. Compute the average rate of change of ff over the interval [−2,6][-2, 6].

  3. Warm-up

    Let f(x)=2x2−2x+5f(x) = 2x^{2} - 2x + 5. Compute the average rate of change of ff over the interval [−1,6][-1, 6].
