First, it is to be understood that logarithms allow a person to subject a number as an exponent of a base. As an example of ways in which logarithm is used to aid us in difficult calculations is when we calculate for the pH of a substance which has a formula of,
pH = -log[H+]
2.35 is equivalent to 235%
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

Answer:
see below
Step-by-step explanation:
3y=6-2x and then
y=2-2/3x
