Average rate of change means find the slope of the secant line. So if there is a function f(x) and you want to find the average R.O.C over the interval [a,b], it would be (f(b)-f(a))/(b-a)
1. (f(3)-f(1))/(3-1)= (0-(-2))/2= 1, so D.
2. Same concept; (8-4)/(3-1)=2, so A.
3. Again, (39-(-1))/5= 8, B.
It's 3.3 because the 2 is in the tenths place and you look at 6 and say is it over 5? Yes it is so the next number after 2 is 3 so your answer is 3.3
Answer:
Hey there!
The correct answer is A. People with a college education are always more successful than those without one. You learn important skills in college that are simply impossible to even know about in high school and middle school.
Let me know if this helps :)
I think it would be c if it were a greater rate I don't know if i am right I'll check back with you guys on the answer
