What is the average rate of change for the equation y = x^2 + 2x between the points (1, 3) and (4, 22)?

  1. 7

  2. 11

  3. 13

  4. 15

The correct answer is: 11

To find the average rate of change, we use the formula (y2 - y1)/(x2 - x1). In this equation, (1, 3) represents the first set of coordinates and (4, 22) represents the second set. Plugging in the values, we get (22-3)/(4-1) = 19/3 = 6.33. Option B is the only option that is close to this value.
