Question

PLEASE HELP
Find the average rate of change of
g(x) = -x^2 +4(x) +1

from x= 3 to x=6
.

Simplify your answer as much as possible.

Answer 1

g(6) = -6^2 + 4(6) +1
g(3) = -3^2 + 4(3) +1

then do I subtract the second equation from the first?

Answer 3

I really dont know how to solve this :( maybe @Michele_Laino or @tkhunny can help you

Answer 4

ok =)
when I plugged in 6
g(6) = -11
when I plugged in 3
g(3) = 4
( not sure If i'm on the right track though or if I literally need to subtract the equations)
