Noah is right the answer is 6.9
2 / 15
This is simpler than you think. Just take the square root of the denominator and of the numerator and stick it back into fraction form. The square root of 4 is 2 and the square root of 225 is 15. Voila: 2 / 15.
The average rate of change of a (continuous) function f(x) over an interval [a, b] is given by the so-called difference quotient,

Here we have f(x) = x² + 8x + 12 and the interval is [-10, -2], so the ARoC of f(x) on this interval is
