Question

Find the average rate of change of the function f(x) = 2x4 +
3x2 ¡ x + 2:
(a) on the interval [0; 3]
and
(b) on the interval [¡2; 0]

Answer 1

Any help would be great. i am so confused

Answer 2

f(x)=2x⁴+3x²-x+2
(please check, because one of the characters posted in the function is not legible).
The rate of change on the interval [a,b]
is given by the change in f(x) divided by the change in x, i.e.
average rate of change on the interval [a,b], Δf(x)/Δx
=(f(b)-f(a))/(b-a) where b≠a.

Give it a try and post your answer for checking if you wish.

Answer 3

Thank you so much. I think i got this one. Calculus is hard.

Answer 4

It's the beginning of the term, and almost everything is hard at the beginning. Once you get the handle of it, it will be fun.
