Math Problem Statement

Find average rate of change of the function on the interval [-3,2]

Find the average rate of change of the function on the interval [-3, 2].

Solution

To find the average rate of change of the function on the interval [3,2][-3, 2], we use the formula for the average rate of change between two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2):

Average Rate of Change=y2y1x2x1\text{Average Rate of Change} = \frac{y_2 - y_1}{x_2 - x_1}

From the graph:

  • At x1=3x_1 = -3, the function value y1=2y_1 = -2.
  • At x2=2x_2 = 2, the function value y2=4y_2 = 4.

Plugging these values into the formula:

Average Rate of Change=4(2)2(3)=4+22+3=65=1.2\text{Average Rate of Change} = \frac{4 - (-2)}{2 - (-3)} = \frac{4 + 2}{2 + 3} = \frac{6}{5} = 1.2

So, the average rate of change of the function on the interval [3,2][-3, 2] is 1.21.2.

  2. What does it mean when the average rate of change is positive or negative?
  3. How can you interpret the average rate of change for different types of functions?
  4. What is the difference between instantaneous rate of change and average rate of change?

Tip: The average rate of change gives you an idea of how the function behaves on average between two points, and it can be visualized as the slope of the secant line connecting those points on the graph.
