Question

For the function f (x) = x2 + 3 Calculate the average rate of change from x = 1 to x = 4

Answer 1

9514 1404 393

Answer:

  5

Step-by-step explanation:

The average rate of change on the interval is ...

  (f(4) -f(1))/(4 -1) = ((4² +3) -(1² +3))/3 = (4² -1²)/3 = 15/3 5

The average rate of change of f(x) on [1, 4] is 5.
