Question

Calculus Help?

Am I right?

And help with b?

use the graph of f' to (a) identify the
interval(s) on which f is increasing or decreasing, and (b) estimate the values of x at which f has a relative maximum or minimum.

Answer 1

something seems to be missing or no?

Answer 2

Yeah :) here's the graph

Answer 3

scary..

Answer 4

i dunno srry. I don't understand the question.

Answer 5

oh and I think its increasing on (-1,-2) and decreasing (1,2)

Answer 6

its ok thanks for looking :)

Answer 7

sorry, you are not right

Answer 8

:( I'm looking at the graph...

Answer 9

got me?

Answer 10

ahhh ok

Answer 11

and what about b?

Answer 12

correct above, f'(x) >0 , f(x) increases look at the graph of f'(x) , it is >0 on (−∞,−1) and (0,1) so, f(x) increases on those intervals it is <0 on (-1,0) and (1,∞), so, f(x) deceases on those intervals
oops you have formula to find critical point that is f'(x) =0 , where are they?
base on the graph, it's = 0 when x = -1, x =0 and x = 1
