3( 2x + 5 )
You can't take x out and you can't take 6 out, 15 doesn't have x and 6 doesn't go into 15, but 3 can go into both 6 and 15 so take out 3. you cannot go any farther.
I am answering this for points, so don’t know for sure but I think you might find 6.9
Answer:
A. 16
Step-by-step explanation:
We have to find rate of change of function from x=3 to x=5
The average rate of change for the interval a≤x≤b is given by:
Rate of change= (f(b)-f(a))/(b-a)
In our question,
a=3
and
b=5
We can see from the table that at x = 3, the value of function is 18
So,
f(a)=18
and
At x=5, the value of function is 50
f(b)=50
Rate of change=(50-18)/(5-3)
=32/2
=16
So the rate of change of function between x=3 and x=5 is 16 ..
Option A is the correct answer..
