Math Problem Statement

Given the function defined in the table below, find the average rate of change, in simplest form, of the function over the interval 24 ≤ x ≤ 96.

Solution

To solve the problem, we need to find the average rate of change of the function f(x)f(x) over the interval 24x9624 \leq x \leq 96. The average rate of change is given by the formula:

Average Rate of Change=f(b)f(a)ba\text{Average Rate of Change} = \frac{f(b) - f(a)}{b - a}

Where a=24a = 24 and b=96b = 96.

From the table provided:

  • f(24)=50f(24) = 50
  • f(96)=38f(96) = 38

Substituting these values into the formula:

Average Rate of Change=f(96)f(24)9624=38509624=1272=16\text{Average Rate of Change} = \frac{f(96) - f(24)}{96 - 24} = \frac{38 - 50}{96 - 24} = \frac{-12}{72} = -\frac{1}{6}

So, the average rate of change of the function over the interval 24x9624 \leq x \leq 96 is 16-\frac{1}{6}.

Here are five questions that expand on this topic:

  1. What is the significance of a negative average rate of change?
  2. How would the rate of change differ if we used a different interval, such as 42x9642 \leq x \leq 96?
  3. Can you explain how the average rate of change relates to the slope of a line?
  4. How can we interpret the average rate of change in a real-world scenario?
  5. What does it mean if the average rate of change is zero over an interval?

Tip: The average rate of change of a function over an interval is equivalent to the slope of the secant line passing through the points corresponding to the endpoints of the interval.
