Let f(x)=x2+6x+11. what is the average rate of change from x = 5 to x = 8? enter your answer in the box.

The correct answer is 19

The average rate of change is 19.

Step-by-step explanation: The given function is

We are to find the average rate of change from x = 5 to x = 8.

We know that if for a function f(x), f(a) = b and f(c) = d, then the average rate of change from x = a to x = c is given by

For the given function, we have

Therefore, the average rate of change from x = 5 to x = 8 will be

Thus, 19 is the required average rate of change.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
