f(x)=x^4-x^2+ 1 x=(3a)

OpenStudy (anonymous):

f(3a)=3a^4-3a^2+1 f(3a)=81a^4-9a^2+1 is this right and is it final answer

hartnn (hartnn):

ys, correct! good :)

OpenStudy (anonymous):

so how can you graph this

hartnn (hartnn):

can't u use a graphing calculator or online resource ? or you need intercepts ?

OpenStudy (anonymous):

i prolly can use calculater but i dont know how to use it, plus i have to show work....but now as im looking...i wont have to graph this, i think the ones that has to be graphed will be simple

hartnn (hartnn):

yeah, because, y intercept is easy (x=0 gives y=1, so (0,1)) but for x intercept (y=0), we need to solve 81a^4-9a^2+1=0 and the roots of x are coming to be complex!

hartnn (hartnn):

here's a graph, if u need

OpenStudy (anonymous):

so r u insinuating 81a^4-9a^2+1 is the final answer

OpenStudy (anonymous):

evaluate each function at the given value and simplify

OpenStudy (anonymous):

thats the directions

hartnn (hartnn):

f(3a)=81a^4-9a^2+1 is absolutely correct final simplified answer.

OpenStudy (anonymous):

when u set it to 0, i thought i was supposed to continue solving

hartnn (hartnn):

i did that to get intercepts from which we could graph...but if you only want to evaluat, then no need of setting anyting to 0 :)

OpenStudy (anonymous):

so u set to 0 because i asked how to graph which isnt necessary....right?

hartnn (hartnn):

correct.

OpenStudy (anonymous):

srry, do yall get paid for helping?

hartnn (hartnn):

not at all! we are glad we can help, that happiness is our payment ^_^

OpenStudy (primeralph):

No we don't get paid. That's the point in helping.

OpenStudy (primeralph):

Not really happiness. Some of us get to meet smart girls and make others look bad here.

OpenStudy (anonymous):

u wanna b my personal tutor. i have a college math corse at itt tech, i graduated in 1998.....ive been in class 4,5 weeks now....im lost. i only had to take algebra 1 in high school, this material wasnt covered in high school...so im tryna remember what i forgot and learn new.... i made a 58 on my 1/4 eXAM

OpenStudy (primeralph):

@dabeezy We will try our best to help you here.

hartnn (hartnn):

you can ask here any type of math question you have trouble solving, we will help you if we can.

OpenStudy (anonymous):

THIS MAN MEETS GIRLS ON A OPEN STUDY TUTOR WEB SITE SMH, ROTFLMFAO

OpenStudy (primeralph):

@dabeezy Yeah well you know. I'll advise that you try Engineering Math by KA Stroud for starters.

hartnn (hartnn):

this site has chat facility for social interaction where we can meet boys and girls of any age :)

OpenStudy (anonymous):

advertise that what?

OpenStudy (primeralph):

....boys and girls and chics.....don't forget the chics.

OpenStudy (primeralph):

*advise. I recommended the book.

OpenStudy (anonymous):

what is it and where is it?

OpenStudy (primeralph):

It's a book. You can get it online of you know your way. Quite popular.

OpenStudy (primeralph):

*online for free.

OpenStudy (anonymous):

if you know your way?

OpenStudy (primeralph):

Okay, just buy the book if you can. Or watch some online videos and all.

OpenStudy (anonymous):

i be doing that sh!t

OpenStudy (anonymous):

our teacher dont teach us pellet, erthang ive learned so far been from you tube

OpenStudy (primeralph):

@dabeezy Of course. Did you expect your teacher to teach? Welcome to earth.

OpenStudy (anonymous):

i cant afford a 60 dollar book, then try to learn one book while studying my math book

OpenStudy (anonymous):

r u serious? in college the teachers dont teach?

OpenStudy (primeralph):

That's why I said "if you know your way, you can get it for free". Maybe back when you were in school, they did, but not very much anymore. No generalization here.

OpenStudy (anonymous):

woow. if i knew this before hand, i wouldnt went back to school yet. i wouldve spentt months trying to remember what i forgot first

OpenStudy (anonymous):

how can i get for free

OpenStudy (primeralph):

Can't change the past.
