Sorry, I don't know this one.

OpenStudy (anonymous):

Whats f(x) Equal

OpenStudy (alekos):

what is g(x) = ?

OpenStudy (alekos):

f[g(x)] = [(x+3)/4]^2 - 4[(x+3)/4] - 3

OpenStudy (alekos):

now just substitute x=9

OpenStudy (anonymous):

IT SHOULD BE -21

OpenStudy (alekos):

no, its not -21

OpenStudy (youngstudier):

I'm sorry, I don't think I've learned this stuff yet.

OpenStudy (haleyelizabeth2017):

Please be patient!

OpenStudy (haleyelizabeth2017):

First, plug 9 into the g(x) equation in place of x.

OpenStudy (haleyelizabeth2017):

Just so you know, I'm not going to give you a direct answer.

OpenStudy (haleyelizabeth2017):

But, I can set it up for you. \[\frac{(9)+3}{4}\] What do you get when you add 9 and 3, then divide the sum by 4?

OpenStudy (haleyelizabeth2017):

@whystudyalonejamescollen55555

OpenStudy (alekos):

yes its -6

OpenStudy (haleyelizabeth2017):

@alekos, please don't give direct answers!

OpenStudy (haleyelizabeth2017):

for the first part. Now plug 3 into the f(x) equation: \(f(3)=(3)^2-4(3)-3\) \(f(3)=9-12-3\) Simplify.

OpenStudy (haleyelizabeth2017):

Yes.

OpenStudy (alekos):

didnt give a direct answer. James already worked it out previously and I acknowledged that he was right

OpenStudy (anonymous):

Yes @alekos was helping me before as well :) thanks guys!

OpenStudy (alekos):

no problem
