Question

f(x) = 9x^3 + 6x^2 -7

Answer 1

sometimes

Answer 2

whats the question?

Answer 3

Use polynomial graph shape and end behavior to determine which of the following could be the x-coordinates at which the relative maximum and relative minimum occur in the given function

Answer 4

what are the options for "which." i feel like if you are going to use OS for homework help, then at least read the question well enough to put it in your own words and not obviously copy and paste. but i digress, and that is my personal feeling.

Answer 5

^ I disagree.

I can't tell you how many times I've seen someone "put it in their own words" and miss an important detail. I like to see the question `as it was asked`.

Pointing out what particular part they're stuck on is helpful though, yes. :p

Answer 6

i dont understand it enough to put it into my own words

a.
The relative maximum is at x = -.44 and the relative minimum is at x=0
b.
The relative maximum is at x=.44 and the relative minimum is at x = -.44
c.
The relative maximum is at x= 1 and the relative minimum is at x =-.44
d.
The relative maximum is at x=.44 and the relative minimum is at 0

Answer 7

i can't figure out how to find the relative max and minimum

Answer 8

if it is calculus class it is easy
if it is not calculus class you are in trouble

Answer 9

i guess putting it in your own words was the wrong way to state that. i meant more so as in, if you are going to copy and paste it into the problem, at least put all of the information. nothing frustrates me more than when someone doesnt copy the whole problem and everyone has to ask "what does the problem ask" and things like that. but again i digress, i am not looking for a fight, just stating simple pet peeves. and i apologize i did on this questions

Answer 10

\[f(x) = 9x^3 + 6x^2 -7\]
\[f'(x)=18x^2+12x\] set equal to zero and solve for \(x\)

Answer 11

Francis, do you remember what the graph of x^3 looks like?Does that look familiar? :o
