Best ResponseYou've already chosen the best response.2wherever you x replace by a+b \[f(x)=3x+2\frac{4}{x}\] \[f(\color {red}{a+b})=3(\color{red}{a+b})+2\frac{4}{\color{red}{a+b}}\]

Best ResponseYou've already chosen the best response.2if for example f(x)=x^2 they ask f(c) \[f(\color{blue}{c})=\color{blue}{c}^22\] just a matter of replacing the dummy variable

Best ResponseYou've already chosen the best response.0what do i do when i set it up like that

Best ResponseYou've already chosen the best response.2that's what they asked you the evaluate a+b standards as some variable

Best ResponseYou've already chosen the best response.2hmm you can simply more if they ask you just depends on the question

Best ResponseYou've already chosen the best response.2in this case i would just leave it that way

Best ResponseYou've already chosen the best response.0what about the second one?

Best ResponseYou've already chosen the best response.2second you gonna do each one separately g(a) g(ab) f(a) after that the results do g(a)g(ab)+f(a)

Best ResponseYou've already chosen the best response.2let me see if you can do g(a)

Best ResponseYou've already chosen the best response.0i thought were supposed to use the equation they gave us tho

Best ResponseYou've already chosen the best response.2what equation?

xapproachesinfinity

Best ResponseYou've already chosen the best response.2you have g(x) right find g(a) by replacing x with a

Best ResponseYou've already chosen the best response.2i broke it down to steps as you can see first find g(a) then g(ab) then f(a) all separately

Best ResponseYou've already chosen the best response.2try to do g(a) first let me see you do it

Best ResponseYou've already chosen the best response.2yes g(a)=23a what about g(ab) now

xapproachesinfinity

Best ResponseYou've already chosen the best response.2use the same function g(x)=23x to find that

Best ResponseYou've already chosen the best response.023(a)23(ab)+3(a)+24/(a)?

Best ResponseYou've already chosen the best response.2that the next step let's not skip do f(a) first

Best ResponseYou've already chosen the best response.2i mean you have the idea but that's wrong because of the sign

xapproachesinfinity

Best ResponseYou've already chosen the best response.2yes now g(a)g(ab)f(a)=23a(23(ab))+3a+24/a

Best ResponseYou've already chosen the best response.2the difference btw what i just did and what you did is i put those parenthesise before 23(ab) because of the sign that came before it

xapproachesinfinity

Best ResponseYou've already chosen the best response.2if ignored that it would be wrong because the sign has to be distribute to 23(ab)

Best ResponseYou've already chosen the best response.2so no what we do it open up the parenthesis 23a2+3(ab)+3a+24/a

Best ResponseYou've already chosen the best response.2we simplify more =23a2+3a3b+3a+24/a =....?

Best ResponseYou've already chosen the best response.0oh okay, thanks so much!!
