Question

Let f (x) = x2 + 2x + 3 What is the average rate of change for the quadratic function from X = -2 to x= to x = 5?​

Answer 1

Answer: 5

Explanation:

The average rate of change for the function f(x) from x=a to x=b is given by :-

The given function : (Its a quadratic function with degree 2.)

The average rate of change for the quadratic function from x=−2 to x = 5 will be :-

[Note (-)(-)=(+)]

Hence, the average rate of change for the quadratic function from x=−2 to x = 5 is 5 .
