Question

Find the average rate of change for each function on the interval [-2,6].
f(x)=-x^4+3x

Answer 1

So easy

Answer 2

Then help please, i don't know the formula.

Answer 3

slope formula

Answer 4

integrate the function from -2 to 6, then divide by 8

Answer 5

oh actually i am wrong and hero is right

Answer 6

\[\frac{f(6)-f(-2)}{6-(-2)}\]

Answer 7

Wow, That rarely happens

Answer 8

lol

Answer 9

So i solve and thats my answer? Thats it?

Answer 10

yup

Answer 11

f'(x) = -4 x^3 +3
the rate = -4 (-2)^2 +3 =-4(-8) +3 = 32+3=35

Answer 12

?

Answer 13

DHASHNI, wth

Answer 14

So i'd do f(-2^4+3*-2)-f(-6^4+18)/6+2?

Answer 15

((-2^4-6)-(-6^4+18)/8

Answer 16

137.75? Sounds right?
