Sorry, I don't know this one.

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

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.

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?

@whystudyalonejamescollen55555
OpenStudy (alekos):

OpenStudy (haleyelizabeth2017):
@alekos, please don't give direct answers!

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
