Solving for x would give me 14 and negative 10 which would lead to the problem looking like so 14(-10-4)=140
Imma go with F just because I think it’s right
9514 1404 393
Answer:
22.5
Step-by-step explanation:
The average rate of change on the interval [a, b] is the ratio ...
(f(b) -f(x))/(b -a)
For your function and interval, it is ...
(f(0.5) -f(0))/(0.5 -0)
Since f(0) = 0, this reduces to ...
average rate of change = 2·f(0.5) = 2(5(0.5)² +20(0.5)) = 2(5/4 +10)
average rate of change = 22.5
I think its either A or C. Leaning more to A. Do you think you could explain the question just a bit more?
