1 answer

To determine the rate of change for each function, we should calculate the slope or rate of change for each function.

  1. Function A: The slope can be calculated using the two points (0, 2) and (6, 7). \[ \text{slope} = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7 - 2}{6 - 0} = \frac{5}{6} \approx 0.833 \]

  2. Function B: We can approximate the slope using the provided points. We can take the change between the first and last points. \[ \text{slope} = \frac{y_6 - y_0}{x_6 - x_0} = \frac{7.09 - 2.50}{6 - 0} = \frac{4.59}{6} \approx 0.765 \]

  3. Function C: The equation is given in slope-intercept form \(y = mx + b\) where \(m\) is the slope. For Function C:

    • The rate of change (slope) is \(1.3\).

Now we have calculated the slopes:

  • Function A: \( \approx 0.833 \)
  • Function B: \( \approx 0.765 \)
  • Function C: \( 1.3 \)

Ordering them from least to greatest:

  1. Function B (approximately 0.765)
  2. Function A (approximately 0.833)
  3. Function C (1.3)

So the order from LEAST to GREATEST rate of change is:

  • Function B
  • Function A
  • Function C

Therefore, you should drag them in this order: Function B, Function A, Function C
