Do you know how to start it?
no
Alright g is on the inside, so you are going to put the function g, into the x of the function f

ok
Does that make sense? Are you able to do it now?
i dont even know what im looking at
haha alright here, -4(10x-6) + 7 I put g(x) into f(x) now just solve
simplify not solve
how do i do that?
first analyze it the question is find f(g(x)) you already know that f(x) = -4x + 7 and g(x) = 10x - 6...but in the question there is no f(x) but there is just an f so what would you do to find f
simplify? just distribute the parenthesis
no not yet
yes you would, from what I said he would
I already went through putting the function g into the function f
you would take away the x from the equation so it would be f=-4+7
i think
;__; what do i do
no you would not
listen to me, you have f(x) = -4(10x-6) + 7
i'm sorry i'll try to find a link that can help you..kk..first what kind of problem is this
algebra
then you just simplify f(x) = -4(10x-6) + 7 -40x + 24 + 7
i mean like equation....ect.
f(x) = -40x + 31, and that is your answer
so b
lets have two opinions first kk
No it is b I promise you
im going to cry
jasmineflvs I came up with one of the answers, you told him to eliminate the x which you DO NOT DO. I promise you it is b, I can show you again if you like
no lets get two opinions and dont cry
Why does he need two opinions? alright thebroski I want you to work it out yourself, start by putting g(x) into the x in f(x)
f(x) = -4x + 7 and g(x) = 10x - 6, so g(x) goes into f(x = -4(g(x) goes here) + 7
just a sec kkk i'll get it and if you were rigght ill give you a medal..kk
thats racists
???
how?? may i ask
.just a sec ((kkk))) i'll get it and if you were rigght ill give you a medal..kk
??? still dont understand why it is racist
Let f(x) = 2x + 2. Solve f-1(x) when x = 4. 1 3 4 10
let me guess you got the answer
no im just terrible at math
f^-1(x) is an inverse equation
that's okay
you need to switch the spots of x and y in the equation given and the solve for y, make sense
?
sorry i can't help you on functions i am behind in Algebra...I'm in 10th grade and I'm still in Algebra 1...sorwie
im in 10th to but math is not my subject i dont understand any of it except 2+2 thats all i understand
lolz
i'm getting a friend to help you on this one
ok got the answer
here f(10x-6)=31-40x
wut
thats the answer
oh right
sorry sir if u want help be more nicer
what do you mean
.Let f(x) = 2x + 2. Solve f-1(x) when x = 4. 1 3 4 10
thebroski, if you're not going to put some effort into understanding the concept of the answer, no one can really help you. stop posting questions with multiple choice answers if you're not ready to learn
dont say any thing without thinking this is a Moderator
i am trying to put effort into this its just that i have a problem with understanding things im just kinda slow.
btw i really dont care if ur the moderator it doesnt give you the right to ban someone because they need help with questions
i'm not going to ban u for asking for help, in fact i'll help you if i can. it just doesnt seem like u really want the help though. sounds like u just want the answer cos it's quite a long thread and u still don't get it... reposting the question with the possible answers doesn't get u so far on this site. be patient, and try at least, to understand :)
ok
ya i could also help u
